Okay, that's a recitation of the facts. Why didn't the Mexican police arrest him? You say there is no evidence that the Mexican government was being paid off. What would you like, signed receipts? Let ME go on the record as saying that he was MOST LIKELY paying someone off. A rich American rapist, living in Mexico, they didn't know he was there, and he wasn't paying anyone off, I'm sorry but that kind of strains cedulity a bit.
As far as the FBI being only "hours away from an arrest", spare me. As far as Mexico "sending him back", that was probably just a gigantic CYOA on the part of Mexico, motivated by a gigantic CYOA on the part of the FBI. There is no doubt in my mind that if Dog had not gone down there, this rapist scum-bag would still be down there sipping Tequila and raping Mexican girls while the local cops continued to collect their bribes and look the other way.
While you gave a recitation of the facts regarding the generation and execution of the warrant, that still doesn't explain why the U.S. government jumped right on this particular extradition request instead of just back-burnering it like they should have. The answer to that question, I believe, is most likely (no evidence) that the FBI was just embarrassed that Dog got to him first while the FBI was playing silly diplomatic games or sitting on their butts.
I've heard lots of legal gobbledy-gook, speculation, and fact recitation of this thread, but no has been able to explain to me why this extradition request from Mexico was not just back-burnered into oblivion. That would be REAL quid-pro-quo with Mexico.
THere is no evidence that the request was recent, or acted on quickly. Dog was arrested back in 2003, so for all I know the mexican government made this request months ago.
According to the news reports, Luster was using an alias and a fake ID in mexico. So it could well be nobody down there actually KNEW who he was. I also don't doubt they didn't CARE who he was -- but that's a far cry from suggesting that Mexico refused to return him to the country, when the fact is that the government never refused to return him, and in fact returned him within a day of arresting him.
