Instead of going to prison like many of the officers involved in this case should have. Convictions for destruction of evidence, false imprisonment, perjury and probably more than a handful of RICO offenses should have been passed out to the cops involved. And that's on top of the original traffic offense.
Police are going to have to get used to the idea that their every action will be recorded. More and more people will have recording devices and as memory becomes more and more available I wouldn't be surprised to see some cameras being clothing or head mounted being able to record all day. I do expect the police to start asking manufacturers to install some type of override, so if the police are blinking a certain IR signal the camera will stop recording, but hopefully people will be able to stop that or at least get cameras that will ignore that signal.
As far as I can recall, there has never been a case in which the courts failed to rule against the police in this. It’s a pretty clear-cut 1st Amendment case. These cops haven’t a leg to stand on.
