You might remember a story from about a year ago of a plumber from Texas whose used truck ended up in hands of Islamist militants in Syria. Last week, the plumber filed a lawsuit against the dealer that bought his truck and he's seeking $1 million in damages. Former U.N. ambassador Mark Wallace, of the non-profit Counter Extremism Project, has been trying to bring attention to the huge number of trucks — specifically Toyotas — the Islamic State has bought.
