Its a lie. And the Mexican government knows its a lie.
Mexican mafia are packing machine guns, hand grenades, and bazookas. They are not getting those from the Brownsville Walmart.
We’ve had many many episodes of Mexican military crossing the border in apparent support of smuggling operations. So if mafia gunmen are packing military hardware, there is another possible source a little closer to home.
The other lie is that Mexico has lost all control of their northern towns and cities. The mexican army was attacked by the narco army a couple of weeks ago in broad daylight. 8 separate army bases were hit at the same time. That takes cajones or they know the Mexican army is weak enough to take them on. The military gun battles are being fought with military weapons, not hunting rifles from Walmart. In some cases the drug gangs have better weapons than the army. And these battles are happening within yards of the border on the south side of the border. For now. Point is that there is a small scale war going on in Northern Mexico for control over that part of the country and our leaders seem to be comfortable to do nothing about it. It will take someone “important” being affected by this for anything to be done by dc.
NOW THAT should be the focus of a Congressional Hearing.. But don't hold your breath ..
