My eyes, unlike yours, are open. To the police society is the enemy, especially the blacks. The police have their own society and protect it, not us.
Maybe it's a great case for segregation in this country. The white communities don't feel that way. We support our police and give them every benefit of the doubt. That's why our neighborhoods are safer.
If you give them the benefit of the doubt that is only because they, being nearly all white, give you the same, until that is you are the subject of their attentions and then you are fucked because they don't seek the truth they seek a conviction, regardless of the truth.
Are the cops required to testify on your behalf? No. Can they use anything, even you not saying anything, against you? Yes. Will they make up evidence and lose evidence that could clear you? Yes. Time and again they do.
Never, ever, speak with the police. When they want to talk to you ask only for a lawyer, over and over again until they very reluctantly grant you your rights. The police are the enemy and that's even more true for darkies.
