The 0-Man says 90% of the weapons used in crimes in Mexico come from the US.
The reality is that 90% of the *weapons they can trace* come from the US, but they can't trace the origin of very many of the weapons, especially all of those AK-47 knockoffs that come through the southern Mexican borders and that are used by all the seriously violent druggies and their Lords.
And, it is commonly thought that Mexican officials only turn over to the ATF for tracing those weapons already thought to have come from the US and used in a "violent" crime.
Using math that is beyond me, the figure seems to be somewhere between 17% (Right-wing Faux News) and 25% (Left-wing Politifact). Who you believe depends on your political leanings and the drum yer beating, but the reality is that far fewer guns are traced to the US than the 0-Man would have you think.
Now, why would he want you to think that?
The problem is that most of the automatic weapons they find in Mexico have markings that clearly show they come from places like Guatamala and China. And the gun and pawn shops don't sell these guns. And that's where the traceability comes in -- not every gun recovered in Mexico is submitted to the ATF for tracing; only those with US markings.
So the 0-Man is using this false statistic as very thinly veiled anti-legal gun propaganda here in the US.
Isn't it about time the Mexican government built a wall along the border to prevent the flow of illegal weapons into their country?
