Here's another story about the case, that people should read. Excerpt regarding the FBI manhunt -- the FBI received the same tip that Dog received, and was on the trail legally with Mexican Government approval:
“We were surprised, but not embarrassed. He’s in custody and that’s the bottom line,” said supervising FBI agent Bob Mack, who, along with other officials, offered several excuses for not getting to Luster before Chapman: There’s lots of fugitives in Mexico. They were unsure of the legitimacy of the tip. They were hours away from catching him themselves. And, to top them all, Luster was a rapist, not a terrorist.
The story I reference is very sympathetic to Dog Chapman, but the facts embedded show that Dog was really just trying to make a name for himself and get some money, and while it suggests the mexicans were looking the other way with Luster, it offers no concrete evidence of that.
Sure!
