Remind me again how mandatory background checks are supposed to stop these people? We can't even stop them when the .gov knows all about them. They had knowledge that this guy had mental issues, they had knowledge about the Tsarnaev brothers, but law-abiding gun owners are the real issue.

We have malfeasance at all levels of the government, we have a government sending guns to drug cartels, we have a government arming al-Qaeda associated "opposition forces" all over the world, but I'm somehow a problem because I like guns.
