Probably wouldn’t have been a bad idea, honestly. Tasers work.
And often, Tasers don't work. You've got one shot, and if one of your two electrodes misses, you're SOL.
Not to mention, if someone is on drugs, a Taser cannot compare to the devastating and incapacitating damage to soft tissue, nerves and organs effected by a jacketed hollow point round.
If you're a few feet away from your attacker.
I don't think you'd be able to get the thing positioned right with a guy straddling you bashing your head into the sidewalk.
