This is a no brainer, the door should swing both ways, you can record me, with voice and I should be able to do the same, I totally approve of the use of car cameras for LE, it has proved very valuable in both what occurred for prosecution, exoneration and training. So many LE videos of traffic stops and during the ticket writing, someone else running into the police car or emergency vehicle. I totally agree that anyone being investigated or during arrest has the right to be videoed, I do not agree, in most instances with no knock warrants, I do understand, sometimes that is the only way, especially here in Dallas, where the whole neighborhood is hooked up, 10 yr olds with cell phones as look outs, to warn when the Swat is on its way, and a lot of superior drug dealers here have reinforced their homes, with entry cages, bust through a door, and you will find yourself in a wrought iron cage, that needs to be unlocked, trapped and tunneled, so they will often tear off whole sides of houses instead of going through doors. I would almost rather have the audio, than the video, context is difficult without it.
