Dear Editor, Re: thirty-round magazines: If you can actually shoot, they're irrelevant. They do let people who can't really shoot just spray the area, so they're a boon to homicidal maniacs. The Second Amendment was a sop to slave owners in case of a slave revolt. The reference in the amendment is to a militia, not an individual. Slave owners would need a militia in such an instance since they would be outnumbered by the slaves. Slaves did revolt periodically; everyone knew that. That's why it was written in.
