Why does our government tolerate this?

Border patrol agent held at gunpoint

For that matter ... why does the Mexican government tolerate this?

It is UNACCEPTABLE for armed people wearing the uniforms of the Mexican military to cross our border and interfere with operations of our law enforcement and border patrol.

You would think it would be in the best interest of Mexico to at least PRETEND to try and deal with this problem.

And, why is the US government providing proper support for our agents ... I don't really think it would take much ... a couple of A-10s or and Apache or two. That might be all you would need. A hummer wouldn't fare very well against either aircraft.
