You have to shoot him,ok,let's say you absolutely have no choice........shoot the f*cing leg,you global idiot!!........man....
I don't know why people always go "Shoot them in the leg!". Y'all are aware you're just as likely to bleed out if they hit you in certain places in the leg, right?
He killed the boy........
Yes. I'm aware.
And as it was already pointed out, this isn't a fictional story. Shooting someone in the leg, or another body part does not immediately disarm a threat nor does it even secure that said person will survive.
This is the problem with these types of things, it's people on the outside judging a split-second decision from an individual who is trained to make threat assessments and respond accordingly. Sorry, child or not -- if you draw a gun on a cop, you're more than likely going to get shot. They don't have the luxury to stop and examine the potential weapon.
Police officers, and even soldiers for that matter, are trained to quickly and effectively dispatch threats to protect the greater good. Not make miracle shots in the heat of the moment.
