People people... I can't claim to know what accually happened, but, lets think abit. The boy was in the middle of an assult when the cop found him. So, from the cops point of view, he was violent.
The kid was hiding in a shed, the cop couldn't see him, this presents the cop with an unknown veariable, has the kid found a weapon of some type in the shed? If the kid had accually cracked the cop in the face with the door, and maybe managed to get his gun... it's not a far strech to belive the cop was in fear for his life...
So, from the cops point of view, we have a violent kid, evading arrest, possible with a weapon now, laying in wait, and tries an ambush attack. "But he's 14..." So? I personally know 13 year olds that are *nearly* as big as I am. If they were to get the jump on me, with a weapon of some sort, I MIGHT accually be in trouble... And IMO, 14 is OLD ENOUGH to know not to RUN from the police.
But, at the end of the day, i don't *really* know what happened. I can't judge if the cop overreacted or not. I doubt anyone here can either. All I do know is that it was tragic, and i feel for his family.
