"victim's family"??? More like the perpetrator's family! They should be ashamed.
This trend in our culture that requires POV video of everything is a severe mental disorder.
This will result in fewer good candidates for police officers and fewer jobs being filled.
There are numerous reasons for no video in any given situation. And the vast majority of the time it is not for nefarious reasons.
--- When a CARRY PERMIT HOLDER kills an attacker, or uses deadly force there are no calls for video proof of these incidents and the case is adjudicated based on evidence as it should be. Is congress going to mandate that carry permit holders wear body cameras ?
