Why are SF police officers such sickos?

For five days, I have seen articles in the local newspapers saying how "great" the cops are. I keep hearing rich bystanders say that "they are just doing their job."

But I know from being there that this is bullshit. I have seen cops go out of their way to beat people harder, hit them with nightsticks more often than they have to, pull people's hair, smash protest signs that they are confiscating, and then stand there in front of you and laugh about it.

That isn't "doing your job."

Furthermore, I can't comprehend how any normal person can stand there in a military uniform and beat/arrest people for having a political gathering on a sidewalk.

These cops are specifically instructed to push people into the street to arrest them, box innocent people in and beat them and send them to jail, etc.

I see that some officers are actually disobeying police orders when it comes time to beat people. But they are more than willing to go through the motions of boxing people in, arresting people for nonviolent protest, and ultimately defend through silence the brutality of their coworkers.

So "just doing their job"? I don't think so.
If it really came down to that, all things considered, I would find a new goddamn job if I was a person with morals.

All it would take is ONE OFFICER to come forward and shed some light on the BRUTAL and ILLEGAL actions they know about in San Francisco police's handling of these historic protests. But where are they?

If a cop won't come forward and talk publicly about this shit, they aren't just "doing their job." They are supporting a corrupt group of police state CRIMINALS who are breaking the law.
