You've been getting all your facts from old exploitation films and pulp paperbacks then?
(Not to mention the fact that it makes white women have sex with negroes and Satanic jazz musicians.)
Good Lord! I hadn't realised about those last two! Better ban that sinful modern Jazz music also! To the arms locker!
You forget that the pot-heads are behind a lot of the robbery and murder, so by strangling their addiction at the source the crime rate will drop. Think of the children!
