These thugs behind a badge are going to cover each others back to the detriment of the entire police force. That alone should explain why the people of Fullerton are angry with them.
As someone wrote earlier in this thread (paraphrasing) these thugs should be held to a higher standard than ordinary citizens.
Currently they hold themselves to a lower standard because to them and the city officials, it appears, think that it was perfectly fine to hold this homeless man down and beat the life out of him.
The officers other than the 6 under investigation should understand that the actions of the 6 officers reflect directly on them. If they can’t hold a higher standard to themselves, they don’t belong on the police force. It’s people like these that are keeping us from even pretending that our country is a Constitutional republic.
