as long as body cams can be turned off (and as seen are sometimes intentionally) or “accidently” can be low on battery and turn off before the things happen that they were meant to record in the first place, then there is a problem with “normal body cam fotage” as then “normal” simply does not even exist.

or said otherwise: what if you could record all your hundreds of visits to banks, then turn your body cam of, rob the bank and later get away with it, because you have footage showing / “prooving” that you were NOT a robber all the OTHER times ?
