This idiot should tell this to my great grandparents, who had the privilege of having armed men break into their house, line them against the wall, and execute them right in front of my 10 year old grandfather, then have all their property and house confiscated, just because they were Counts.
What happened to your family was a crime, but it had nothing to do with police criminality, misconduct, nor breach of the trust of the public who employs them.
Police react, and they have no legal responsibility to do anything other than react. In America, the Supreme Court has upheld that law enforcement has no obligation to protect the citizens not in their custody.
When those we have trusted break that trust, and harm us, we must band together to fight them, because they are no better than those people who murdered your family.
I am very sorry for your loss.
