If you go to Tancredo's website and read the incident description, you'll see that the BP agent first saw a helicopter southbound into Mexico before he encountered the HumVee. Whether that helicopter was doing recon or actually returning from carrying cargo into the U.S., I don't know, but I suspect both Customs and USAF saw it on their radars. There's not much that a Citation or even a Mohawk could do even if they could get there in time, but hey, an A-10 could get there about as fast as the Citation and then proceed to chop both the helicopter and the HumVee into scrap metal.
The aftermath of which would be suitable for framing, and eventual posting to FR, for gratuitous chortling.
that these gentlemen happened to be in the general area when I was hunting for some good pix..... ;-)
I've seen one of those 30mm cannons firing at dusk from spitting distance and the 6ft column of green flame that comes out the business end is enough to put the fear of ___ in anybody...
