Thanks!
Clayton Cramer wrote in one of his books that some of the first gun control laws sought to keep firearms out of the hands of free blacks. Antebellum gun laws sought to prevent a slave revolt ala Nate Turner (or what happened in Haiti to the French). Slaves could, with consent of their master, possess and use firearms; presumably to control the varmints that threatened crops. Post-war firearms restriction laws were intended to make it safe for the KKK to lynch black folks.
