Police just want to go home safe to their families when their shift is over.
A desire that has zero to do with what happened here, nor does it justify this.
Everyone who commits a crime wants to supress the evidence and go home afterwards.
Big whoop.
Horsecrap
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.
Looks like you might have forgotten your /sarcasm tag.
