Update: More from McClatchy on the man who hurled teh shoes at teh (outgoing) prez, Muthathar al Zaidi:
Zaidi works for an Iraqi satellite television station based in Cairo. Friends said he covered the U.S. bombing of Baghdad’s Sadr City area earlier this year and had been “emotionally influenced” by the destruction he’d seen. They also said he’d been kidnapped in 2007 and held for three days by Shiite Muslim gunmen.
