You didn't even read the Inspector General's Report report did you? I was so conservative in my estimate of effectiveness that I used the propaganda in the press showing how successful it was.
The Inspector general found that the actual daily reports of effectiveness ranged from 10% to 30%, and that the experienced guards estimated a 5% to 15% rate of effectiveness. That means that they were only catching 5% to 30% of the border jumpers.
If Steel and concrete fences with a ratio of 25 guards per mile can only catch 30%, a person would literally have to be a complete idiot to think that we could come anywhere close to ever sealing the border.
Michael Savage might get away with fooling the Neanderthals into believing the border could be sealed, but any candidate who ran on a "sealing the border" platform would be laughed into obscurity.
If you look closely you will notice that "With tweaking it could be workable." was my reply to your question about Tancredos guest worker program. If you would like to find my response to your post about Op Gatekeeper you can look to the post directly above the "tweaking" post.
