Here you will see a video showing several Seabrook, NH police officers slamming a prisoner in their custody into a wall and pepper spraying him for no apparent reason.
The video is surveillance camera footage from 2009, but it as just uploaded to Youtube this week. Now, three officers have been placed on leave pending an investigation. I guess the lesson here is, "If a cop fucks you up for no good reason in view of a surveillance camera, always, always, always make an effort to get the video of the incident."
Also, another lesson would be "It sure is easy to stand around looking like a smug prick when the guy you're beating up is half your size and outnumbered 3-1."
