Just because a bunch of teens are being disrespectful doesn't mean the cops should start pulling guns. A few months ago police pulled up in a car seeing a young boy with a gun, they shot him within a few seconds of pulling up and were still in their car. He was a little boy playing with a gun. But I guess you'll make an excuse for the cops in this case too like so many have that since he was in a public place and the red cap was pulled off the gun so that it looked real it was ok. Just like if this cop which pulled his gun and shot the teenager that ran up close to him. Someone out there would say it was ok for the cop to shoot him because he ran up to the cop.
What I have to say is police are supposed to be better, better trained better prepared to deal with these situations but instead in America its increasingly shoot to kill and evade questions and since were the law we can do as we please. Oh and if you didn't know cops use hollow point bullets so their chances of killing someone with one shot is greatly increased. They don't care about justice and a guy getting his day in court nope they want the perps dead, a dead person cant testify in court.
