I'm not too sure of that. Seems to me they will turn on each other at the drop of a hat if it means that the other guy takes the fall and they get away. Also, look at how they treat each other in every other part of the world. They have no loyalty, except to themselves, and whoever is buying them off at the time. Race be damned, it is all about selfish indulgence. Why else would there be so many single AA mothers living in the hood, if AA's were so loyal to each other.
JC,
Not to be disagreeable but I grew up in the south; all my life have I lived here. I come from a working class background, and went to integrated schools. You're going to have to trust me on this when it comes down to a perceived white vs. black issue. They will side with their own race, even though they knew it may be wrong.
Friends of mine who are black have verified what I have observed. Like all things like this, it's not 100%, but it's close.
