From the AP:

A man was arrested at Detroit Metropolitan Airport after officials say they found him carrying more than $78,000 in cash and a laptop computer containing information about nuclear materials and cyanide.

I’m sure it’s just for peaceful purposes.

The Detroit Free Press adds:

Authorities said Sisayehiticha Dinssa, a U.S. citizen who was born in Ethiopia, was arrested after getting off an airline flight from Amsterdam. They said he had spent four months in Nigeria on unspecified business.

Maybe Joe Wilson sent him?
