The evidence is overwhelming the public is unquailed to judge if a police behaved properly and the press is either unwilling to help or just as unqualified which should hardly be surprising if you have spent time with a journalist major.
The should be cross department reviews and oversight of the footage but BLM has shown us how much facts matter in these cases. How many people want to not only have to make split second life or death decisions but then have it recorded and judged in the court of public opinion? Cops are far from perfect but make that job so grossly unappealing and dangerous to not just your life but your personal liberty and families well being will do nothing but give us a lower caliber of police officer because the best qualified will choose other options. Would you take a job a police officer under the current environment? I looked at hard about twenty years ago and I am damn glad I decided against it.
