Every time the police act in this manner, they are teaching us by example that violence is acceptable behavior.
They are also showing a lack of self control.

The police are not our friends.

Don't ever trust the police, and never talk to the police, if you can help it.

By the way, when exercising your right to remain silent, you need to express its exercise outright.

...that statement is just silly.

There are too many people with bad intent out there and too many people too weak to protect themselves.....we DO need police, but we need better police and need more police training\education and swift punishment for abusive police.

the police couldn't protect my family and me. People shoot up schools, and the police can't protect the kids. They can beat up liberal protestors. They can harass minorities. But they have a hard time protecting us.

but if a cop does it, then it's all good? rrrright

It's the prosecutors, who are also not your friend.

Kicking his legs out from under him may seem mild but you can get seriously hurt from a fall of only three feet. You could break a knee-cap for example, like my father once did when he slipped on an icy sidewalk. Even if the boy was "profane" as mentioned, and chest-bumped another officer, it doesn't give the cop the right to retaliate to get even. At a minimum the officer should be required to receive counseling for his anger issues lest he inflict much greater harm on someone next time.

I slipped on a deck and ended up breaking my elbow. Both my radius and ulna were up around my bicep area. Most painful thing that I had ever gone through.

A lot of cops have shown their true ilk with no reservation since the videos of OWS surfaced. There are some that are psychotic and should never be given a position of power. This isn't to say that all cops are bad just like you can't lump an any other group together because there are a few bad apples. I went to school with a guy like that who became a cop. He said, and I do quote, "I have a badge now and I can do anything I want to someone and they can't do shit about it." I told him he would probably end up getting shot one day for pissing someone off and being a general asshole.

I've met some really good cops who were just good people in general and I have met some that REALLY should be darted and given a guest shot on wild kingdom. I think it all comes down to why they became a cop in the first place.

Here are some good reads on what kind of people police forces hire:
