I am going to repeat what Police Officers are trained for:Are you simply being deliberately obtuse?
There were apparently at least 2 pieces of pertinent information that were not passed on to the officers. 1) the caller had mentioned several times that the 'gun' might be fake and 2) that the person in question appeared to be a juvenile.
Are you telling me that you can't see how that information just might affect the manner in which the officers approached the scene?
The bottom line is that a 12 year old kid was killed for doing exactly what 12 year old kids have been doing since humans climbed out of the trees and it's interesting how little that seems to matter to more than a few folks here.
take all incidents involving a gun as if its a real gun.
It is not an Officer's job to give any credence to your opinion on what may be a real or fake gun.
I know this is hard for some pot smoking lefties like you who can't grasp the simple truth:
obey what an Officer tells you.
He or She is not there for fresh air. An Officer is there on duty to enforce order. Anyone running around brandishing a gun or pulling out a gun when told to raise their hands up is risking their lives because Officers are trained to stay alive.
News flash: 12 year-olds shoot people too. It happens a lot in drug and gang infested areas.
You are probably one of those 'concerned citizens' who don't understand why Police shoot people who refuse to drop a knife. Look up Tueller Drill. And maybe you should learn how and why police Officers are trained the way they are and why they do what they do. This way you won't appear so ignorant about things.
