Input: Crawl of outlinks from wikipedia.org started March, 2016. These files are currently not publicly accessible. Properties of this collection. It has been several years since the last time we did this. For this collection, several things were done: 1. Turned off duplicate detection. This collection will be complete, as there is a good chance we will share the data, and sharing data with pointers to random other collections, is a complex problem. 2. For the first time, did all the different wikis. The original runs were just against the enwiki. This one, the seed list was built from all 865 collections. ||||| The NYPD is recommending that businesses identify "safe rooms" where employees can hide if a shooter invades the workplace — because hiding under the desk is no protection from gunshots. 
  
 Det. Kathleen Thompson told a gathering of business leaders, security professionals and media on Thursday that four weapons were tested against the kind of wooden desk typically found in offices. 
  
 Bullets from a .38-caliber Smith & Wesson handgun, a 9mm Glock handgun, a 12-gauge Mossburg shotgun, and an AK-47 all crashed through the desk. A better choice of hiding place is behind a file cabinet, which withstood ammunition from all but the AK-47. 
  
 "The more layers you have the better protection you have," Thompson said. "You want to have as many layers between you and that gun."

 Thompson said that if workers can get out of the building and away from the shooter quickly, they should do so. But there are times, she said, when "your best option may be not to evacuate." 
  
 That's why the department, which studied 230 "active shooter" events to come up with its recommendations, suggests businesses create safe rooms with thick walls, solid doors, and as few windows as possible. 
  
 Those who barricade themselves inside should put their phones on silent, not vibrate, and try to block the door. 
  
 Deputy Commissioner for Counterterrorism ‎John Miller said NYPD personnel train for active-shooter situations in facilities designed to look like offices. The department expects its first responding patrol officers ‎to engage with the gunman. 
  
 Between 2000 and 2013, 486 people were killed in such attacks — which happen at a pace of one every 3.5 weeks and can involve meticulous preparation by the perpetrators. 
  
 "Even with emotionally disturbed people ... a lot of them demonstrate a high degree of careful planning during the incident," Miller said. "They manage to stay fairly organized." ||||| Workplace shootings are becoming so common that the NYPD is now providing training on how workers caught in such a situation should respond. The latest session was held for members of the media. NY1’s Dean Meminger filed this report. 
  
 The NYPD showed a training video to members of the media to dramatize what could happen if a gunman roams the workplace. It was part of a training session in response to the growing number of mass shootings, which now occur about once every three and a half weeks in America. 
  
 "Seventy percent of that happened in the workplace. Sixty percent of them are over before the police get there. And that's that 4 to 9 minute window,” said Deputy Commissioner of Counterterrorism and Intelligence John Miller. 
  
 The NYPD regularly holds seminars like the one they held Thursday, but the training session at police headquarters was scheduled for the media after a reporter and cameraman in Roanoke, Virginia were shot dead last week by a former colleague on live television. 
  
 Officers say it could happen anywhere, to anyone, but when police respond—remember they are in charge of your safety. 
  
 "Follow the instructions of the officers as they arrive. You are not reporters now in this situation. Don't start asking them questions. Let them get in there, you get out. If they tell you go a certain way, go a certain way. If they tell you get down on the ground, get down on the ground,” Det. Kathleen Thompson told the trainees. 
  
 According to the NYPD, the rule of thumb is ABC: “Avoid,” “Barricade,” and if all else fails, “Confront.” 
  
 That means in an active shooting, the first priority is avoiding the gunman. Next, try to barricade the person from where you are. Only as a last resort should you confront and fight. 
  
 The NYPD has stepped up training for patrol officers on mass shooting scenarios. Those officers often arrive before the specialized teams do. 
  
 "We are pushing a rescue, what's called a rescue task force concept which is pairing officers up with EMS and fire," said Det. Raymond McPartland. 
  
 "Officers say it may be scary to think about but every business and family should conduct drills on how to survive an active shooting situation.

Output:
Most mass shootings happen in the workplace and most of them are over before police get there, according to the New York City Police Department, so workers need to know how to react. The NYPD held a training session for members of the media yesterday in response to last week's TV shooting in Virginia and journalists were told to follow officers' instructions and forget about asking questions if they are caught in the middle of a mass shooting, NY1 reports. The NYPD says people should remember "ABC" for Avoid, Barricade, Confront: getting away from the shooter if you can, barricading yourself in if you can't, and confronting them only a last resort, as set out in a department safety pamphlet. To expand on the "Barricade" part, reporters were told to get "as many layers at they can" between themselves and the gun and were shown a video demonstrating how a typical wooden desk provided no protection against two commonly used handguns, a shotgun, and an AK-47, reports NBC. A filing cabinet, however, withstood fire from everything but the AK-47. The NYPD, which suggests workplaces set up "safe rooms" with thick walls, says it studied more than 200 events to come up with its survival recommendations, which include setting your phone on silent instead of vibrate when hiding. (A University of Alabama reseacher says his study explains why America leads the world in mass shootings.)
