I would have guessed that all LA based LEO cars would have always on dash cams.
but I would be really surprised if there wasn't any recording from a business?
There is ALWAYS disagreements over "who ran the light"
It is rare for anyone to say "the accident was my fault-I ran the light-injured that person"
No video-
perhaps there is an event recorder -cop car braking-
and an accurate RED LIGHT event recorder after accident-should line up with GREEN LIGHT RECORDER
There MUST be event recorders for both?
