Lying about police brutality

I'm trying to understand what the left thinks of police officers, and it doesn't make sense

One minute the police are hardworking union members. They are public servants who hold society together, and it's a scandal that Republicans and Tea Party members want to reduce or restrain taxes and risk putting them out of work.

The next minute the police are evil thugs who make unprovoked attacks on innocent protesters. These police officers can't stand the anti-rich and pro-union statements the peaceful Occupy Wall Street and anti-globalization protesters make and assault them.

For some reason, those same police officers don't get in fights with the low-tax anti-union right wing protesters. These same protesters who want to reduce the benefits of public employees, such as for the police department, are never brutalized.

I understand that there's a diversity of opinion on the left, and individual progressives should not be expected to hold views consistent with every other leftist.

But the logic still doesn't make sense if you believe the fable that modern American police are fascist thugs who make a habit of attacking left wing protesters. The simple answer is the protesters are lying.

We already know Occupy Wall Street is filled with people who want to smash things and fight the police. A third in a recent poll said they believe in violence to advance their goals. There's no great mystery here, the protesters are causing violence and then pretending to be the victims.
