A short film by Paul Sullivan that chillingly breaks down the creepy tactics New York City police used to intimidate and harass protesters, and arrest them for expressing their first amendment rights in public space. In these examples, it seems they used "the momentum of arrests" to deter the spirit of the crowd–not because the individuals shown here actually posed a threat to the public, or had harmed anyone or done anything bad.
