“I can see if it’s one bad cop but the ones covering up for him are as responsible as the bad ones”.
The rot is nation wide and far too many departments are no longer committed to their oath of office but to their department and their fellow officers.
That they are a bunch of thugs in uniform is, in the end, our fault. The public can remove the Police Chief at each election, or recall him if abuses are too egregious to wait for the next election.
Control your servants or they will control you.
This has always happened throughout history. Power + human nature corrupts.
