It's pretty simple. If the "law" claims you are guilty, then the average person has to believe it on some level.

Even in the black community, being in prison kind of means that you actual did something, to the minds of your fellows.

And, at this point, as an individual, you can't do much about it. Not that will fix the problem.

So instead you have to protect yourself and others.

1. Always be polite. To everyone. Go out of your way to be kind and genteel.

This won't give you a magic force field, but it will make you less likely to be a target.

2. Have all your paperwork in order and at hand, at all times when out in public. If stopped you have to be ready to present it. (Welcome to the Nazi controlled U.S.?)

3. Follow all the laws, at least in public and never, ever brag or talk about the laws you broke.

4. Give the appearance of being law abiding all the time. Dress nicely, but not more so than those around you. Don't ape or mimic "cool criminal styles".

5. Avoid the police. Unless you are being killed or currently raped in the behind, don't call them. Don't have anything to do with them if you can at all help it.

Now, this won't save you 100% of the time, but it will help a lot. There are dozens of modern rules to follow, but it comes down to not giving anyone reason to think you're other than you seem, a law abiding and polite person.
