They're the same people, Mick - just different names. Yes, the Bush Administration has politicized border enforcement just like they've tried to tie everything else to their ideology - but the people doing the job still do it more-or-less the same.
It's not so much the execution of things that's haywire - it's the philosophy behind it. I suppose that it may be different in raids in large meat processing plants away from the border, where agents don't have experience in doing raids day after day - but my experience in California is that Border Patrol agents are pretty professional in the way they do things.
