Police taze 17 year old for vaping
Looks like unwarranted assault by the police to me. But it would be nice to see the full video. Unless they had reasonable suspicion he had a weapon or something, or had been previously violent in the encounter, I don't see how the taze is appropriate. They seemed to taze when he reached for his backpack.
The real question is why did they have the tazers drawn at all? That's only appropriate if there's some kind of threat or continued refusal to comply with lawful orders. I didn't see him NOT complying in that clip, but we don't have the full encounter.
