At the moment he shot, Wilson was not engaged in a hand to hand struggle for the possession of the gun, though he had been shortly before and had reason to believe he would be again shortly.
Looked the Taser issue up. Apparently Wilson chose not to carry his because he thought it too large and awkward.

He didn't have a taser because he made the choice not to carry it. Which I suspect he regrets.
I guess a thief who robs a store and fights with a cop should be allowed to just get away (while telling the cop he is too much of a p.... to shoot him)?
May I assume you live nowhere near any “Michael Browns”?
The witnesses alone cleared the cop; do you find fault with their testimony?
If you use a taser and miss you’ve then got to dump the taser to draw your pistol and you may not have enough time. If I didn’t have backup I wouldn’t risk playing with a taser.
