I'm trying to remember this correctly. He was riding around in a taxi cab trying to dig up business or perform work on the day he was taken into custody. I have no idea what equipment is used to fix radio towers, but certainly more than what can be fit in a cab maybe?
He was wandering around in the dark "acting suspicious". So he was looking for work in the dark?
Imagine an American leftist radical Jew (by birth only) wandering around the worst sections of Baghdad with an English-Arabic phrase book.
"Excuse me, I'm looking for Al Queda. Can you help me find Al Queda? I love Al Queda. Al Queda is my friend. I have an important message for Al Queda. Can you help me find Al Queda?"
My guess is, he found Al Queda.
Cruising, no mention of a girl friend as yet?
