Input: A grand jury will begin hearing evidence tomorrow in the police shooting death of Ferguson, Missouri, teenager Michael Brown, as violent clashes continued in the St. Louis suburb. 
  
 Witnesses are scheduled to appear before the grand jury, Ed Magee, a spokesman for St. Louis County Prosecuting Attorney Bob McCulloch, said in a telephone interview today. The shooting sparked more than a week of violent protests in Ferguson. 
  
 The state grand-jury probe comes as federal officials are starting a civil-rights’ investigation into the death of the unarmed black teenager. President Barack Obama has ordered U.S. Attorney General Eric Holder to go to Ferguson and meet with FBI agents and Justice Department lawyers handling the probe into the circumstances of Brown’s death.

 Police fired tear gas at protesters and 31 people were arrested in Ferguson last night after demonstrators refused to leave a section of the city that has been the epicenter of protests. Protesters hurled bottles and Molotov cocktails, and gunshots were fired, wounding two people, according to police. The victims, both male, weren’t shot by police, authorities said. 
  
 Brown, 18, was killed Aug. 9 by Darren Wilson, a white Ferguson police officer, after being stopped on a city street, Police Chief Thomas Jackson said earlier.

 Officer’s Testimony 
  
 Wilson has the right to testify before the grand jury, Magee said. It’s not clear how long the proceedings will take or how many witnesses will be called, he said. 
  
 Greg Kloeppel, Wilson’s lawyer, declined in a telephone interview to comment on the grand jury. Kloeppel is chief legal counsel for a local chapter of the Missouri Fraternal Order of Police. 
  
 Evidence is still being collected and the probe is “far from being finished,” so there’s no timeline for the case, Magee said yesterday. 
  
 The grand jury must decide whether Wilson violated the law by shooting the teenager and whether he should face charges ranging from manslaughter to murder, said Gordon Ankney, a former assistant county prosecutor who now does criminal defense work in St. Louis. 
  
 Three Autopsies 
  
 Three autopsies were conducted on Brown’s body. Forensic examinations were done by county officials and a pathologist hired by Brown’s family. The federal government’s autopsy was conducted yesterday. 
  
 The family’s pathologist said yesterday the teenager was shot six times. The examination, conducted by former New York City chief medical examiner Michael Baden, shows at least two gunshot wounds to Brown’s head. 
  
 Those shots, one of which exited around his eye, probably caused fatal damage to the brain, Baden said yesterday. 
  
 The separate examinations shouldn’t cause evidentiary issues at a subsequent trial, Ankney said. 
  
 “I don’t think multiple autopsies will complicate things,” Ankney said. “Things such as entry and exit wounds are pretty easy to establish. It’s trying to interpret what those wounds mean that can lead to debate.” 
  
 The grand jury will have to decide what led to the shooting, said John Appelbaum, a criminal defense lawyer. 
  
 “If the grand jury finds the shooting was justified, he won’t face any state charges,” Appelbaum, in private practice in Arnold, Missouri, south of St. Louis, said in a telephone interview. 
  
 A police officer has authority to use deadly force if he reasonably believes a suspect presents a threat, he added.

(AP) — Police and protesters in Ferguson were finally able to share the streets again at night, putting aside for at least a few hours some of the hostility that had filled those hours with tear gas and smoke.

 The St. Louis suburb still had plenty of lively protest Tuesday over the fatal police shooting of Michael Brown. And tensions rose briefly when someone hurled a bottle at officers. 
  
 But the overall scene was more subdued than the past five nights, with smaller crowds, fewer confrontations and no tear gas. Police said they still made 47 arrests, mainly of people who defied orders to disperse. 
  
 The slight easing of tensions came the day before Attorney General Eric Holder was to visit Ferguson to meet with FBI and other officials carrying out an independent federal investigation into Brown's death. 
  
 In a letter published late Tuesday on the St. Louis Post-Dispatch website, Holder promised a thorough investigation while calling for an end to the violence in Ferguson. He said the bond of trust between law enforcement and the public is "all-important" but also "fragile." 
  
 Arrest patterns "must not lead to disparate treatment under the law, even if such treatment is unintended. And police forces should reflect the diversity of the communities they serve," Holder wrote. 
  
 He said the Justice Department would "defend the right of protesters to peacefully demonstrate and for the media to cover a story that must be told." 
  
 The department has mounted an unusually swift and aggressive response to Brown's death, from conducting an independent autopsy to sending dozens of FBI agents to Ferguson in search of witnesses to the shooting. 
  
 A grand jury also could begin hearing evidence Wednesday to determine whether the officer, Darren Wilson, should be charged in Brown's death, said Ed Magee, spokesman for St. Louis County's prosecuting attorney. 
  
 Wilson was recognized during a Ferguson City Council meeting in February, getting special recognition for what Police Chief Thomas Jackson said then was his role in responding to a report of a suspicious vehicle, then struggling with the driver and detaining him until help arrived. Jackson said the suspect was preparing a large quantity of marijuana for sale. 
  
 Missouri Gov. Jay Nixon said Tuesday that he would not seek the removal of the prosecutor overseeing the investigation into Brown's death. 
  
 St. Louis County Prosecutor Bob McCulloch's deep family connections to police have been cited by some black leaders who question his ability to be impartial. McCulloch's father, mother, brother, uncle and cousin all worked for the St. Louis Police Department, and his father was killed while responding to a call involving a black suspect. 
  
 Nixon said he would not ask McCulloch to leave the case, citing the "well-established process" by which prosecutors can recuse themselves from pending investigations to make way for a special prosecutor. 
  
 Departing from that process, Nixon said in a statement, "could unnecessarily inject legal uncertainty into this matter and potentially jeopardize the prosecution." 
  
 McCulloch, a Democrat, was elected in 1991 and has earned a reputation for being tough on crime. 
  
 Ferguson city leaders said the mayor, the City Council and municipal employees have been exploring ways to increase the number of African-American applicants to the law enforcement academy, develop incentive programs to encourage city residency for police officers and raise money for cameras that would be attached to patrol car dashboards and officers' vests. 
  
 "We plan to learn from this tragedy, as we further provide for the safety of our residents and businesses and progress our community through reconciliation and healing," officials said in a public statement. 
  
 Benjamin Crump, an attorney for Brown's family, said the 18-year-old's funeral and memorial service would be Monday. The time and location had not been finalized.

 After a week and a half of tense confrontations, arrests and recriminations in protests over the police killing of unarmed teenager Michael Brown, officials in Ferguson, Missouri, promised Wednesday to explore sweeping changes in the city's law enforcement structure — including the possibility of putting cameras on all officers' vests. "We plan to learn from this tragedy," city leaders said in a memo lamenting the "discord and heartbreak" that have visited the community since Brown, 18, was shot to death Aug. 9. 
  
 The statement, which was unsigned but was attributed to "our mayor, members of the City Council and city employees," said the city was exploring short- and long-term responses to "the concerns raised as a result of this devastating series of events." Most immediately, they asked residents to stay home at night to "allow peace to settle in, and allow for the justice process to take its course." But they also said they were reviewing wide-ranging changes in police operations, including the use of cameras in police cars and attached to officers' vests, working to boost the number of African Americans applying to the police academy, and requiring officers to live in the city of Ferguson. 
  
 Critics of the police say that had officers been wearing cameras, much more would be known about both the shooting of Brown and about interactions between police and protesters afterward. An online petition urging the Obama administration to work for a "Mike Brown Law" requiring all state and local police departments to use such cameras had reached more than 123,000 signatures by Tuesday evening.

Output:
Ahead of a visit from Attorney General Eric Holder today, officials in Ferguson, Missouri, say they want to make big changes to law enforcement and end the "discord and heartbreak" that has followed the police shooting of unarmed teenager Michael Brown. A statement released by city leaders says it is looking at changes including requiring all police to wear cameras, hiring more African-American officers, and requiring police to live in the city, reports NBC, which notes that a petition seeking a "Mike Brown Law" to require state, county, and local police to wear cameras has now received more than 127,000 signatures. In a St. Louis Post-Dispatch op-ed, Holder promises a full, fair, and independent investigation into the shooting. He praises the bravery of police officers who put their lives on the line, but also stresses that "good law enforcement requires forging bonds of trust between the police and the public." Trust "requires that force be used in appropriate ways," he writes. "Enforcement priorities and arrest patterns must not lead to disparate treatment under the law, even if such treatment is unintended. And police forces should reflect the diversity of the communities they serve." Another person was shot and killed by police in St. Louis yesterday, but Ferguson was more subdued last night than it was the previous five nights, the AP reports. Police still made 47 arrests, but the crowds were smaller and no tear gas was fired. A grand jury will begin hearing evidence today on whether Darren Wilson, the officer who shot Brown, should be charged, reports Bloomberg.
