You left out the part where you get attacked when the perp grabs for your gun.
You don't 'scuffle' with a policeman if you want to live.
There were four witnesses. If it was a decent shoot, why did he need to be declared mentally disabled for life due to a trauma on duty? If he was that delicate, shouldn’t he have been screened out?
I don’t have the facts, of course, and I’m usually sympathetic to the police (although I’ve met some jerks on occasion). But, this sounds a lot more like the idiot in Florida who shot a supine therapist with his hands in the air than like Ferguson and Officer Wilson, where the officer was both justified and vilified, and had to leave the force.
A “brief” scuffle ..... they were fighting over each others underwear....?
