Correction: common carrier passenger transport is NOT one of the prohibited-by-law CCW locations here. However, the local transit authority does post the buses with the gun-buster decals. And, while I was on handgunlaw.us, I did find out NM does make carry on a public bus a misdemeanor.
Guardian Angels should patrol the buses. Pay them by dismantling Americorp and the Peace Corp. That’s close to a billion bucks. They come with their own cell phones. Minimal training.
