The Smallest Minority on earth is the individual. Those who deny individual rights cannot claim to be defenders of minorities. - Ayn Rand
Yep, armed, with "clubs and knives." (Got that direct from one of the participants.) When the police arrived and refused to defuse the situation and left, the young people were far outnumbered, and Ron Walters called someone for help. Help was there in ten minutes, and the blacks who responded didn't show up empty-handed. The white "young toughs" saw the a larger crowd of blacks coming in the front, and decided that leaving via the back door was the better part of valor.
Is it true that gun control was more or less implemented in this country as a means to keep blacks disarmed?
Research the "Black Codes" and the history behind the U.S. v. Cruikshank decision.
From the Dred Scott v Sanford opinion :
"It [citizenship] would give to persons of the negro race, who are recognized as citizens in any one state of the Union, the right to enter every other state, whenever they pleased.... and it would give them full liberty of speech in public and in private upon all subjects upon which its own citizens might meet; to hold public meetings upon political affairs, and to keep and carry arms wherever they went..."
There is another good write-up on the subject, with sample laws, available here. Reason doesn't do too badly at summing it up, either.
We're still seeing this : the states with more limited concealed carry also have higher populations of blacks. In May Issue areas, minorities including blacks and hispanics are not only less likely to get a carry permit than whites when adjusted for population, but even when adjusted for the lower rates that blacks and hispanics apply!
That'd get Jesse Jackson's panties in a bunch if we were talking about a school, but when the Hickman v Block decision said minorities had no standing on the issue, scarcely a word was heard.
