Every occupation has its drawbacks. You probably think that they need to worry about shooting it out with rival gangs in turf wars. But there has been a rash of kidnappings in Phoenix. You can read about it in Kidnappings cross the border. Here is an exerpt:
"The kidnap victims are typically drug- or immigrant-smugglers, who are seen as inviting targets because they have a lot of money, they can raise large sums of cash on short notice, and they are unlikely to go to the police, for fear their own shady dealings will come to light."
I guess this is the high price of success. Many cases go unreported. Apparently the victims' families don't want to call the police. So they are more of a target and they can't go the authorities.
