Clamping down on illegal border crossings, however, had an unintended consequence: It upset agreements among the cartels over smuggling routes, sparking yet more violent competition.
I would have said that the clampdown "set off violent competition."
It gets worse. I personally briefed John McCain on my theory. He listened inventively, and then went on to make up a story about what stopped smuggling across the Goldwater bombing range.
Opposition among certain people to a border fence --- or any real borders security system --- is so intense that they will sacrifice our security --- and the lives of tens of thousands of Mexicans --- to defeat it --- and the media will back them up.
These are the same people and the same media --- who are behind the Gang of Eight immigration legislation.
