Unfortunately, there are no law-abiding blacks, just as there are no law-abiding people left in the entire United States of America. We have so overly legislated at the local, state, and federal levels that it is impossible for anyone to go through a single day without violating some law. We've had those laws imposed on us by our peers and masters without our specific agreement. We violate those laws and take no consequence for it. We violate those laws and have them inconsistently enforced. All of those things are designed to produce a profound and complete disrespect for law.
Throw away that useless term, "law-abiding". Start using the phrase "good and righteous" instead.
