The US attorney who is responsible for this whole fiasco is a close associate of Bush. I can't believe that this wasn't done as part of a program to discourage anyone from interfering with illegal entry to this country possibly including drug traffic.
Johnny jackass Sutton goes way back with George Bush and is a close adviser now. Sutton's fiefdom includes Crawford Texas
I think you're right on... Bush has pushed his open borders agenda from the time he walked into the White House. You can bet that some crooks in America are making big $$$ out of the drug trade, and don't want it to stop.
