I think the call about someone with a gun is legit/justified but lets be real here...those cops didnt give the kid a chance to put the gun down. Its like putting your blinker on as you start to turn instead of 20/30/50 feet back to give the cars around you some notice.

Poor decision making led to an uneccesary death in this situation. Other cases like the guy who was shot in walmart for having a gun over his shoulder...that was just testosterone & rhoid fueled murder.
