Blacks are always suspect and can be shot on sight by police for mere suspicion of being armed. This happens in even open carry states. It happens hundreds of times a year nation wide. Many criminals get their guns by way of gun shows in red states, sometimes using "straw" purchasers. The NRA has helped facilitate these sales by fighting every gun control law. For example, most guns in Chicago are bought in Indiana where the gun laws are much more lax than in Chicago. BTW, The NRA even fights research into why we have so many gun deaths. The police live in  fear because they know there are enough guns in the population for every man, woman, and child.
