There is a long history, from Sacco and Vanzetti and before. This was a just one example that was covered on Friday's Democracy Now! broadcast. Others were murdered in their beds or by other means. See
http://www.democracynow.org/2007/11/30/former_black_panther_details_brutal_police . Read/watch/listen to the whole interview, and ask yourselves what kind of monsters are being defended by those who ally themselves with US imperialism, and what do they expect them to do here if you threaten their power.
So they were beating me and asking me questions. And when they started asking me questions, they started telling me about what I was supposed to have done, that if I didn’t cooperate and tell them what happened, they were going to continue to do it. So they put plastic bags over my head and held me back while five or six police officers stood around me, hitting me and kicking at me. They were like kicking each other trying to get their licks in. They were hitting each other trying to hit me. And all I could do was sit there and just try to brace myself and anticipate blows coming. And then they’d take the bag and put it back over my head, and they’d wait ’til I’d just about pass out, and they’d snatch it off.
And at that point, one was standing—would stand behind me, and he would take the palms of his hands, and he’d slap my ears, and my ears would just be ringing. He did that a number of times, and fluid began to run down the side of my face, and I couldn’t hear anything. It was just ringing.
And at that point, they dragged me to another room, and then they take me out of the chair, and they had the chains on my ankles, and they would drag me through like a gauntlet of police on both sides, and they were like kicking me and calling me names. And they continued that and put me in another room, and then I could hear John Bowman and I could hear Ruben Scott, and they were hollering. They were doing basically the same thing to them that they were doing to me. This went on for—you lose conception of time, but it seems like it was forever. And they continued this and continued this.
And then, they said that they wanted to talk to me. They gave me a break. They wouldn’t give me water or anything like that. They leave me alone for maybe five to ten minutes, and then they come back, and then they start asking me questions about the Black Panther Party, about police murders in different parts of the country. I tell them I don’t understand what they’re talking about. I didn’t know. So they resume back to asking me questions concerning, well, what was I doing in New Orleans. And every time I got ready to try to explain why I was in New Orleans, they would continue to beat me, and I couldn’t get anything out, say anything.
