Second loose observation from a trip to the Mexican border:
The charge that Arizona had to pass an anti-immigration bill because the federal government isn't enforcing the border proves patently ridiculous once you go down there and take a look.
As Bill Wolff pointed out, we saw Border Patrol agents everywhere we went in Nogales -- hanging around downtown, cruising along the border fence every five minutes, eating in the local restaurants. They are everywhere, and they are vigilant. In the clip above, Santa Cruz County sheriff's Lieutenant RJ Rodriguez starts to show us a place where a wash prevents the building of a tall fence. We stood there for a couple of minutes talking. Sure enough, here came the Border Patrol, driving through, checking us out.
At one stop, we lucked into an assignment sheet for the Border Patrol. It's got enough proprietary info on it that I don't want to post the document itself, but I will tell you that it, too, shows how flooded the region is with enforcement -- with marksmen and mounted officers and officers on bikes and mention of Wackenhut transport. Nogales felt like a peaceful town with a whole lot of uniformed folks. If they're failing to seal the border, it may be because the border cannot be sealed.
