Guns don't stop crime. Neither does all the law enforcement officers on the job stop crime. What guns do is stop a specific criminal from doing a specific crime. And if the criminal in the act reaches ambient temperature, then they will do no more crimes. Even if they live, it's likely that the crime they attempted was stopped. That's never a bad outcome. Crime will only be stopped when enough criminals are shot to doll rags to put extreme fear of death into the rest of them. Criminals having a deathly fear of their victims would be a good thing.
