There is a major error in this article. She states that gun control was started with the Sullivan act in New York, but it was truly started by Southern Whites after the Civil War to keep guns out of the hands of black citizens.

It goes back considerably further than that.

From my .sig database:

Gun Control laws aren't enacted to control guns, they are enacted to control people: catholics (1500s), japanese peasants (1600s), the irish (1920s), jews (1930s), blacks (1960s), the poor (always)...

I will grant that for "blacks" I was thinking of the 1968 GCA, enacted through fear of race riots in the big cities.
