I discussed some recent events in Mexico before, "Call me Ahab" has now dug up some interesting tidbits, some rather intersting information the CNN chose to leave out of their story.
He finds out how criminals are trying to smuggle guns into Mexico, i.e. the "people willing to break the law" loophole. Guns bought illegally, being transported illegally ... what about that "gun show loophole" then? You want them to pass background checks? They are passing background checks!
Seriously, read the original CNN article, and Ahabs post. Scoop out my previous post on the entire thing if you missed it.
