I'm all for cops tasering people as long as they warn 'em first. And he did. I think it's a good weapon for cops to have, more effective than a beating with a baton. And with less damage done to the victim.
maybe the voltage should be less. i've only been shocked with a taser once, and it hurt like fuck, but then again I was like 12. And i'm sure the voltage was WAY less than what they are shocking people with now.
