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. While this was a Ford truck, the case, he says, illuminates how a black market trade across the Turkish border has benefitted Islamists. "Turkey has to do a much better job in shutting their border and preventing this porous trade from seeping into the border," Wallace said.
