How do drugs get into prison? Why do the lowest members of a drug ring get serious time, while the top guy gets off scot free?
"This quaint Mexican custom will come to America along with the immivasion."

We are going to be blessed with all the nice quaint folksy Mexican customs. "Bribe as you go", kidnapping and paying ransom for relatives I'm sure will also be among the most popular.
