I thought Wilson had no taser because the department couldn’t afford them for all cops; that was my understanding.

Once Michael Brown was close enough to be halfway in the car, Wilson has to use deadly force to protect his gun.

Here's the problem with that. The physical fight through the door of the car ended. Brown ran away. Wilson got out of the car and followed him, ordering him to stop. Brown turned and charged Wilson, who shot and killed him while he was still some distance away, though closing rapidly.

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.
