U.S.: A dozen years after Columbine, jerks still trying to set off bombs
- 1999 In one of the deadliest school shootings in U.S. history, two Columbine High School students killed a over dozen people, then themselves. The Colorado tragedy caused a spate of copycat incidents nationwide and led to much cultural hand-wringing over why it happened.
- 2011 On Columbine’s 12th anniversary, Southwest Plaza Mall, located less than two miles away from the site of the shooting, had a close call with an apparent bomb threat. The suspect placed explosives in an area of the mall usually closed to the public. A security guard caught it before it went off. source
