On May 30, 1990, New Jersey Gov. Jim Florio signed a ban on assault weapons into law, making good on one of his campaign promises and giving New Jersey some of the strictest gun regulations in the country. Thirty-six years later, that law has been left in tatters by the 3rd Circuit Court of Appeals, which ruled last week that the Second Amendment disallows the state's prohibitions on semi-automatic rifles and magazines with over 10 rounds of ammunition.
