Very risky advice for ANYONE. Doesn't matter your race, the police don't like people to stick up for themselves. Judges tend to frown on this behavior as well, even if it's morally right. The truth doesn't matter when the judge doesn't care.
EDIT: That's not to say that all judges will allow these kinds of questionable abuses, just that there are enough that you're kind of taking your fate in your hands in a more substantial way than say driving a car or taking an airline flight.
Very risky advice for the nonwhite.
