> Are you willing to concede most guns used by criminals in Mexico come from the United States?

No -- nor am I willing to assert the opposite, because I have no knowledge of the topic. I will ask, though: why is the place of manufacturer of guns used by criminals is Mexico something worth worrying about?

> And that, if it is easy enough to smuggle guns from red states into Mexico to commit crimes, it stands to reason it is even easier for red states to do the same to blue states?

Well, yes, of course. But I assume that this will be the case regardless of any attempted policy at any level of government, because I do not believe suppressing the movement of firearms is an attainable goal at any scale in the first place.
