Citizens have every right to film police on public roads and in public places.
P-hack, it depends on the DVR, but the three models of car DVRs I've owned take ~50 MB to record 2 minutes of HD MP4 video, or ~70 MB to record 2 minutes of HD MOV video. They simultaneously record an auxiliary camera VGA file of about half that size. So, at 75 MB for 2 minutes of MP4 video, or 100 MB for 2 minutes of MOV video, a 32 GB SD card will let you go back through 10-14 hours of video before it loops to overwrite older files.
