Goldblog defends conceal carry:

The population of concealed-carry permit holders in the U.S. now exceeds 9 million, and this group is responsible for very little crime — they commit crime at a rate lower than the general population, and lower than police officers, and they certainly, as a rule, don't open fire on anyone who looks threatening. They are not the problem, and concealed-carry generally is not the problem. It may even be part of a solution, until such time as a giant magnet appears over the continental U.S. and sucks into the sky America's civilian-owned weapons, or until the gun control movement convinces the majority of Americans who believe in private weapons ownership to open a debate about the 2nd Amendment.
