Someone only interested in petty larceny isn&#x27;t carrying a gun right now for two reasons. They could pawn it for money and if they get caught it will add far more years to their sentence than petty larceny.<p>Someone who uses a gun illegally today, will use one when they&#x27;re illegal. At best making guns illegal would stop some domestic murders, but that would have to be weighed against a massive number of people going to jail for not obeying, country wide stop and frisk, and New Orleans style door to door SWAT raids to confiscate.
