By Scott Stewart Not all grassroots militants who want to conduct a terrorist attack are created equal. As we have previously discussed, this is true in several aspects, including personal intellect, drive and capability . But recent events in Russia and the United States have highlighted another dimension of this inequality, that of location. On Dec. 13, Terry Loewen, an avionics technician working at the Wichita Mid-Continent Airport in Wichita, Kansas, attempted to drive what he believed to be a vehicle bomb onto the airport's tarmac area, using his employee badge to gain access. Loewen, a convert to Islam who had been radicalized by material he accessed via the Internet, believed he was about to conduct a suicide bombing operation at the behest of al Qaeda in the Arabian Peninsula.
