“ You see, that’s another thing. When you talk about a revolution, most people think violence; without realizing that the real content of any kind of revolutionary thrust lies in the principles and the goals that you’re striving for - not in the way that you reach them. On the other hand, because of the way this society is organized; because of the violence that exists on the surface everywhere - you’d have to expect that there are going to be such explosions. You have to expect things like that as reactions. If you are a black person and live in the black community all your life, and walk out on the street every day seeing white policemen surrounding you… 

When I was living in Los Angeles, for instance, long before the situation in L.A. ever occurred - I was constantly stopped. The police didn’t know who I was, but I was a black woman and I had a natural, and they, I suppose; thought that I might be a quote, ‘Militant’. And when you live under a situation like that constantly… and then you ask me whether I approve of violence… I mean, that just doesn’t make any sense at all… whether I approve of guns. 

I grew up in Birmingham, Alabama. Some very, very good friends of mine were killed by bombs. Bombs that were planted by racists. I remember, from the time I was very small, I remember the sounds of bombs exploding across the street; our house shaking. I remember our father having to have guns at his disposal at all times, because of the fact that at any moment we might expect to be attacked. The man who was at that time in complete control of the city government - his name was Bull Connor - would often get on the radio and make statements like, 'Nig—s have moved into a white neighborhood, we better expect some bloodshed tonight’. And sure enough, there would be bloodshed. After the four young girls who lived… one of them lived next door to me; I was very good friends with the sister of another one, and my sister was very good friends with all three of them, my mother taught one of them in her class. My mother… In fact, when the bombing occurred, one of the mothers of the young girls called my mother and said, 'Can you take me down to the church to pick up Carol? We heard about the bombing and I don’t have my car.’ And they went down, and what did they find? They found limbs and heads strewn all over the place. And then after that, in my neighborhood, all of the men organized themselves into an armed patrol.
