 Florida Gov. Rick Scott broke with President Donald Trump on Friday and rejected calls to arm teachers with guns to prevent school massacres. 
 
 "I disagree with arming teachers," Scott said. "My focus is on bringing in law enforcement. I think you need to have individuals who are trained, well trained." 
 
 Scott also defied the National Rifle Association by unveiling a sweeping plan to boost school security that would bar "violent or mentally ill" people from purchasing weapons, prohibit persons under the age of 21 from buying or owning guns, and outlaw so-called bump stocks that make it possible for semi-automatic weapons to fire faster. 
 
 “I want to make it virtually impossible for anyone who has mental issues to use a gun,” Scott said. “I want to make it virtually impossible for anyone who is a danger to themselves or others to use a gun.” 
 
 But the Republican governor, who is believed to be eyeing a Senate run, declined to ban the semi-automatic AR-15 type rifle that Nikolas Cruz allegedly used to killed 17 people on Valentine's Day at the high school in Parkland, Florida. 
 
 That was a key demand of the Marjory Stoneman Douglas High School students who survived the shooting. 
 
 "Banning specific weapons is not going to fix this," said Scott. 
 
 An NRA member, Scott said he didn't consult the powerful gun lobby about his proposals. But it appears to be a sharp break with the organization that has 300,000 members in Florida, and that Scott has relied on in the past. 
 
 There was no immediate response to Scott's move from the NRA headquarters. But its chief lobbyist in Florida, Marion Hammer, called it "gratuitous gun control." 
 
 "We oppose punishing law-abiding gun owners," Hammer told the Tampa Bay Times. 
 
 Scott also called for spending $450 million to put a law enforcement officer in every school (one for every 1,000 students), hiring mental health professionals whose only job would be counseling students, and upgrading school security with metal detectors, bulletproof glass, reinforced doors and other measures.

 The governor's plan calls for a new "see something, say something" hotline, website and mobile app. And to help pay for it, Scott said he is considering abandoning more than $180 million in planned tax cuts and urged lawmakers to temporarily shelve plans for pursue money for hometown projects. 
 
 Scott's announcement came a day after Trump expressed support for arming teachers — an idea that many critics are calling a "colossally stupid idea." 
 
 Also, Scott's move to keep guns out of the hands of the mentally ill appears to be an about face for the governor, who signed a bill in 2011 that barred doctors from asking patients whether they own a gun, unless the provider "believes that this information is relevant to the patient's medical care or safety, or the safety of others." 
 
 A Florida federal appeals court in February 2017 ruled that some of the provisions were unconstitutional, including the part that prevented health providers from asking whether patients owned guns. 
 
 Trump in February 2017 rolled back an Obama-era regulation that made it harder for people with mental illnesses to purchase a gun. 
 
 While making his announcement, Scott took a swipe at Sen. Bill Nelson, D-Fla., accusing him of not doing enough to combat gun violence. Nelson quickly swiped back. 
 
 "The governor’s plan doesn’t do one thing to ensure comprehensive criminal background checks or ban assault rifles, like the AR-15," Nelson said in a statement. "His leadership is weak and by recommending raising the age to 21 he is doing the bare minimum. Enough is enough. We need to get these assault rifles off our streets and expand criminal background checks for anyone acquiring a gun.” 
 
 The developments came on the heels of revelations that Scot Peterson, the Broward County sheriff's deputy assigned to protect Marjory Stoneman Douglas High School, never went inside the school or tried to stop the accused 19-year-old gunman.

He is Bill Nelson, not Ben. ||||| (CNN) A week after one of the deadliest mass shootings in modern US history, Florida Gov. Rick Scott announced a comprehensive plan to keep students safe in his state, including suggestions to raise the minimum age to buy a gun, keep weapons out of the hands of the mentally ill and ban the sale of bump stocks. 
 
 A former student fatally shot 17 people at Marjory Stoneman Douglas High School in Parkland on February 14, sparking renewed and heated debate over the middle point between Second Amendment rights and student safety. 
 
 "We must take care of our kids," Scott, a Republican, said at a news conference announcing his three-part plan. 
 
 Kai Koerber, a student at Stoneman Douglas who was there the day of the shooting, called the plan "a step in the right direction." 
 
 "This is not the end of the line, but we thank Governor Scott for hearing our concerns, and taking steps to secure a better future for the sons and daughters of tomorrow," he said.

 The governor also called for tougher background checks and waiting periods to buy firearms; requiring mentally ill people who have been involuntarily committed to temporarily surrender weapons; and the allocation of hundreds of millions of dollars toward improving security in schools and mental health services. 
 
 "Keeping guns away from dangerous people and people with mental issues is what we need to do," he said. 
 
 "No one with mental issues should have access to guns. It's common sense, and it is in their own best interest -- not to mention the interests of our communities. And much of what I'm proposing involves giving law enforcement the ability to stop people from harming themselves and others, while giving them the tools to keep our schools safe." 
 
 Broward County Sheriff Scott Israel, a Democrat who was re-elected in 2016, was pleased with the news. 
 
 "Thank you Gov. Scott and state legislative leaders for proposing a gun and school safety package that incorporates nearly all the ideas (Broward Sheriff's Office) and other sheriffs suggested. This is a strong first step in giving us the proactive ability to keep Florida safer," his office tweeted from its verified account . The targeted high school is in Broward County. 
 
 Other Democrats don't think the proposals would go far enough. 
 
 "We can beef up mental health screenings, raise the age for gun purchases and dream up other stop-gap measures, but the threat to our children and our citizens will continue until we finally take bold action to ban assault weapons designed for the battlefield from easy access in our communities," Florida Senate Democratic Leader Oscar Braynon said, referring to semiautomatic, assault-style rifles like the AR-15 the shooter at Stoneman Douglas used. 
 
 Scott, who noted that he is a member of the National Rife Association, said he's not calling for a ban on all firearms. 
 
 "I know there are some who are advocating a mass takeaway of Second Amendment rights for all Americans. That is not the answer." 
 
 In response to questions about calls for a ban on AR-15-style rifles and other semiautomatic guns, the governor said that "banning specific weapons and punishing law abiding citizens is not going to fix this. What we have to do is we have to really focus on the problem. We've got to take all weapons away from people with mental illness, people who are threatening themselves or threatening others." 
 
 Part 1: Keep guns away from dangerous people 
 
 Scott said the plan will address strengthening gun laws to keep "guns away from dangerous and violent people." 
 
 -- Part of that includes creating a "Violent Threat Restraining Order," which permits a court "to prohibit a violent or mentally ill person from purchasing or possessing a firearm when either a family member, community welfare expert or law enforcement officer" presents evidence to the court of a threat of firearms violence.

 -- It calls for strengthening "gun purchase and possession restrictions for mentally ill individuals under the Baker Act. If a court involuntarily commits someone for treatment under the Baker Act because they are at risk of harming themselves or others, an individual would be required to surrender all firearms and not regain their right to purchase or possess a firearm until a court hearing." 
 
 -- People who "are subject to an injunction for protection against stalking, cyberstalking, dating violence, repeat violence, sexual violence, or domestic violence" would be prohibited from possessing or buying a firearm. 
 
 -- Enhanced criminal penalties should be created for threats to schools, including "social media threats of shootings or bombings." It also calls for enhanching "penalties if any person possesses or purchases a gun after they have been deemed by state law to not have access to a gun." 
 
 -- Exceptions on the age for firearms purchasing include active duty and reserve military and spouses, National Guard members, and law enforcement. 
 
 Scott said he disagrees with the notion of arming educators, saying teachers should teach and police should police. 
 
 "My focus is on bringing in law enforcement. I think you need to have individuals that are trained, well-trained. My focus is let law enforcement do the keeping us safe and let teachers focus on teaching." 
 
 Part 2: Keeping students safe 
 
 Scott proposed a $450 million initiative for student safety, calling for the presence of a resource officer in every public school and giving sheriffs' departments the power "to train additional school personnel or reserve law enforcement officers" if local school boards ask.

 The plan requires "mandatory active shooter training" and says faculty and students must be involved in "active shooter drills." It calls for an increase in funding for safe school infrastructure, such as metal detectors, steel doors and upgraded locks. 
 
 Scott called for an anonymous K-12 "See Something, Say Something" hotline, website and mobile app, funding "to require access to dedicated mental health counselors to provide direct counseling services," the creation of "threat assessment" teams at each school, and "crisis intervention training for all school personnel." 
 
 Part 3: Expand mental health initiatives 
 
 The plan outlines a $50 million allocation for mental health initiatives, including the expansion of mental health service teams, a Department of Children and Families case manager embedded in every sheriff's department, and matching grants for sheriff's offices to set up special law enforcement teams to work with DCF case managers. 
 
 "There is nothing more important than the safety of our children. Our kids deserve nothing less. Fortunately, our economy is booming, and we have the resources to protect our schools and our students. And, if providing this funding means we won't be able to cut taxes this year -- so be it. And, if we have to give up some of the projects we all hold near and dear -- so be it," the governor said. 
 
 Stoneman Douglas students speak up 
 
 Koerber wasn't pleased with the proposal to give sheriffs' departments the authority to train "additional school personnel" if local school boards request it: 
 
 "Gov. Scott's Action Plan proposes the arming of teachers, if that is the wish of the district. In no way do I, or any of my friends, feel that the arming of teachers is a solution to the issue of gun violence in schools. 
 
 "Nonetheless, we are very happy to see the implementation of a gold standard age for the purchase of firearms, as well as the placement of more law enforcement officers based on the population of a school campus."

 Kyle Kashuv said he is "a bit concerned over the infringement of Second Amendment rights," a reference to the requirement that people be 21 or over to buy firearms. 
 
 "When you are 18 you are legally tried as an adult yet you are not considered mentally fit for a weapon." 
 
 But he favors other aspects on the plan, including the waiting period for background checks, extra school resource officers, mental health funding, the hotline and school building improvements. 
 
 "I think mental health and background checks are necessary," he said, adding that he also understands why the bump stock ban is necessary. 
 
 Isabella Pfeiffer seemed surprised to hear the governor's proposal. She left a meeting with Scott on Wednesday feeling a bit defeated. She said she didn't think he was actually listening to the students. 
 
 But she is a fan of most of the ideas presented Friday. 
 
 "We were super happy to see they were considering raising the age to 21 to own a rifle, I think that was one of the points we advocated for the most," she said. ||||| Meghan Petty is comforted by her father Ryan Petty during a press conference to discuss H.C.R. 22, which designates April as a month of kindness for the state of Utah and honors the lives of the victims...

 TALLAHASSEE, Fla. (AP) — Among the newly released recordings of 911 calls from deadly Florida school shooting, the parents of a 17-year-old girl can be heard telling a dispatcher that their daughter is texting from a classroom where the door's glass was shot out. "Three shot in her room. Oh my God. Oh my God," the mother says, raising her voice. 
 
 As Florida's Republican governor keeps everyone in suspense about whether he'll sign the legislature's response to the massacre of 17 people by a teenager with an assault rifle, the 12 minutes of radio transmissions released by the Broward County Sheriff's Office highlight the chaos at Marjory Stoneman Douglas High School. The material includes 10 of the 81 recordings of frantic calls by students and parents. 
 
 The excerpts show a deputy on school grounds first thought the loud bangs were firecrackers, then realized they were gunshots — yet he never ran toward them. Other responding deputies and officers desperately tried to sort through a chaotic scene, treat the injured, lock down the school and locate the shooter. 
 
 The bill Gov. Rick Scott is weighing narrowly passed Florida's House and Senate. It falls short of what he wanted and what survivors of the massacre demanded, and both teachers unions and the National Rifle Association are opposed. 
 
 But the families of some of the 17 students and staffers who died signed a letter urging Scott to "quickly sign this historic legislation into law." 
 
 "We know that when it comes to preventing future acts of school violence, today's vote is just the beginning of our journey. We applaud the members of the Florida Legislature that courageously voted against their own political self-interest to do the right thing for the safety of our schools. This Time Must Be Different!" the letter read, in part. 
 
 Scott said he plans to meet with those families on Friday. 
 
 "I'm going to take the time and I'm going to read the bill and I'm going to talk to families," said Scott, who had received top marks from NRA for supporting gun-rights measures in the past. He broke with the lobbying group after the shootings, and his new stance reinvigorated the gun-control movement. 
 
 The measure would raise the minimum age to buy rifles from 18 to 21, extend a three-day waiting period for handgun purchases to include long guns, and ban bump stocks that allow guns to mimic fully automatic fire. 
 
 As for schools, it would create a so-called guardian program enabling school staffers with law enforcement training and school district approval to carry concealed handguns on campus. It would create new mental health programs for schools and establish an anonymous tip line where students and others could report threats. It also seeks to improve communication between schools, law enforcement and state agencies. 
 
 The NRA opposes raising age limits to buy weapons or imposing new waiting periods. In a statement Thursday, NRA and Unified Sportsmen of Florida lobbyist Marion Hammer called the bill "a display of bullying and coercion" that would violate Second Amendment rights and punish law-abiding citizens. 
 
 Teachers, meanwhile, called on Scott to use his line-item veto power to zero out the $67 million set aside for the program to train and arm school employees. The Florida Education Association on Thursday sent a letter to Scott saying the only people who should have guns in schools need to be trained law enforcement. 
 
 The governor, who is expected to seek a U.S. Senate seat later this year, has called for raising the minimum age to purchase any type of gun, but he does not support arming teachers. Instead, he wanted lawmakers to adopt his own $500 million proposal to put at least one law enforcement officer in every school. 
 
 The governor has 15 days to sign the measure, veto it or let it become law without his signature. 
 
 Sen. Bill Galvano, a Bradenton Republican and one of the main sponsors of the legislation, says he expects Scott will sign it. 
 
 "The bill is far too comprehensive for the governor to let a few provisions prevent the positive changes this bill embodies," Galvano said. 
 
 President Donald Trump congratulated Florida lawmakers, saying they "passed a lot of very good legislation last night." Trump also said Thursday that the White House is working on a plan to ban bump stocks, and efforts to enhance background checks were "moving along well" in Congress. 
 
 Andrew Pollack, whose daughter was among those killed, said more needed to be done, but there's enough good in the bill that it should pass. 
 
 "My precious daughter Meadow's life was taken, and there's nothing I can do to change that. But make no mistake: I'm a father, and I'm on a mission. I'm on a mission to make sure I'm the last dad to ever read a statement of this kind." 
 
 The suspect in the attack, Nikolas Cruz, a 19-year-old former Marjory Stoneman Douglas High School student, faces 17 counts of first-degree murder and 17 counts of attempted murder for the massacre. 
 
 Cruz's public defender has said he will plead guilty if prosecutors take the death penalty off the table and sentence him to life in prison instead. Prosecutors have not announced a decision.

– Just over a week after the murder of 17 people at Marjory Stoneman Douglas High School, Florida Gov. Rick Scott unveiled a plan Friday to keep his state's students safer: a $500 million proposal to ban bump stocks, restrict people under age 21 from purchasing guns, and prohibit the "violent or mentally ill" from buying weapons, NBC News reports. "I want to make it virtually impossible for anyone who is a danger to themselves or others to use a gun," Scott said, per the New York Times. The age restriction would mark Scott's first big rebuff of NRA policy, per the Washington Post. "I'm an NRA member (and) a supporter of the Second Amendment," Scott said. "I'm also a father and a grandfather and a governor. We all have a difficult task in front of us balancing our individual rights with our obvious need for public safety." Among the initiatives included in Scott's plan are revamping building security to include metal detectors, better locks, and bulletproof glass; placing a "law enforcement officer in every public school"; and working more on "mental health initiatives." What Scott isn't pushing for: banning the AR-15 rifle, which was the type of weapon used in the shooting, and arming teachers, as President Trump and others have called for (to much criticism) in recent days. "Banning specific weapons … is not going to fix this," Scott said. He also said he'd rather see "well-trained" members of law enforcement brought in to protect schools than hand weapons to educators. "We must take care of our kids," he said, per CNN. On Wednesday, the NRA said it will fight any attempt to raise age limits, saying that move would "[punish] law-abiding citizens for the evil acts of criminals."
