Remember that guy who was accosted and then arrested by a bunch of hyped-up TSA employees at the Albuquerque airport in 2009? Despite being well within his rights to not show ID and film the airport’s public areas, the group of swarming TSAers and law enforcement were having none of it. Phil Mocek was causing a “commotion” (even though he was completely calm), and the authorities weren’t going to let a little thing like real laws get in their way.
Officer: This is a federal checkpoint. You can’t do it [film] here.
Mocek: I’ve checked into it and I know that I can do it here.
Officer: Well, you can be arrested, then you can check into it more.
Nice! Arrest first, check laws later.
Last week, Mocek was acquitted on all four charges, including failure to obey an officer and concealing his identity.

The only laws cops know are contempt of cop laws, i.e., obstruction, interference, failure to obey an unlawful order, “illegal” videotaping, and whatever else Johnny Law’s little brain can think of.
And cops will continue to violate laws in the name of ‘contempt of cop’ until there are real consequences for illegal arrest and civil rights violation, namely jail time.
Right now the most you can do, if you’re rich or can find a sympathetic attorney, is sue. The cop’s employer ends up paying for the defense and any judgement, which means the only person punished is the taxpayer. The cop won’t even get a lecture.
