Earlier this month in San Angelo, anti-Islam Guandolo conducted one of his day-long seminars, "Understanding the Jihadi Threat to America." A flier for the program said it would put "terrorist attacks into perspective" and "identify specific jihadi threats in Texas."
The program — which Muslim advocacy groups say promotes racial and ethnic profiling — qualified as continuing education for Texas law enforcement officers, who must take 40 hours of credit every two years.
