Second Amendment

I've often thought that while I should, of course, have the right to any weapon I can buy, I'm not so sure that the guy down the street should be allowed to carry anything more than a plastic butter knife, non-serrated. That leads to the idea that if people are to have access to guns, perhaps there should be some requirement that they have some training. Larry Correia, however, points out that states with a training requirement are no safer than states with no requirement whatsoever. Mandatory training sounds like it would make things safer, but it doesn't. And policy needs to be set on the basis of what really works, not what sounds like it would work.
