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.
Remember, testimony showed that T’s shirt was hanging some 4” from his body - enough to stop a Taser electrode from doing its job.
