From 2008 to 2011, I was a guest lecturer at the Federal Law Enforcement Training Center (the primary DHS training facility, located in coastal Georgia) and at Joint Special Operations University (which brings foreign officers to learn of U.S. irregular warfare, located in Tampa). At both venues I was asked to lecture on the history of terrorism.
I did so in an even-handed and comprehensive manner, exploring the issue across place (Europe to East Asia), time (ancient Assyria to al-Qaeda), and ideology (religious: pagan, Jewish, Christian, Hindu, and Muslim; and political: right-wing, left-wing, anarchist, environmentalist, etc.). Only 14 of the 44 PowerPoint screens in my presentation dealt with Islamic terrorism, although several of those actually mitigated against the concept.
Nonetheless, in June 2009 I was told that I could no longer lecture at FLETC, because the edict had come down from the new Obama administration that "no trainer who uses the term 'jihad' shall henceforth be used." (This was over two years before the Obama administration was openly hostile to realistic training about Islam.)
