Thank you for following up on this, Heidi.

Potential bright spot in this mess: I have observed multiple victims of police misconduct become very interested in matters of police transparency and accountability. Look behind many so-called serial requesters (of public records held by police) and you will find incidents similar to that which the people who were targeted by police violence at Sea-Tac last week experienced.

Arresting people then releasing them without charge, away from the demonstration and/or after it has ended, is an extremely effective way to neutralize a political demonstration without all the hassle of prosecution and zero need for incriminating evidence. However, when police assault protesters, those people typically are charged--with assaulting a police officer. The more I have spent observing the policing of protests, the more evident these patterns have become.

@2: There just might be some cameras at the airport, recordings from which would be useful for confirming or refuting Renton PD's claims.
