What a bunch of crap to even question the Officers....
"Three shots. Why not one that would bring him down?"
Because HE WAS ARMED. Whether or not the gun was real is irrelevant.....those Officers had to make sure the threat was decisively eliminated.
"I know that my son wasn't perfect, but he was a great kid."
Yeah, he sounded great!
Walk into a classroom....coldcock a kid in the face, and then brandish a firearm at the Police inside of a school.
Play stupid games......win stupid prizes.
I hate to sound callous, but I have no sympathy for the kid, and hope the Officers involved don't let this ruin their personal psyche(s) for what was a justified use of force.
Sad.
