[Robert DeLong]

Why are liberals always so surprised that gun laws do not accomplish the intended goal? Only law-abiding citizens obey laws.

[Campion]

My theory is that liberals think people are all basically good, so if they do bad things, it's because something in their environment made them do a bad thing. So fix the environment -- e.g., make guns harder to get -- you fix the problem.

Except that the premise is wrong, so the conclusion is also wrong. People aren't made to do bad things by inanimate objects in their environment, they do bad things because of the world, the flesh, and the devil.
