Scouts Train to Fight Terrorists, and More, By Jennifer Steinhauer. The New York Times, May 13, 2009.
The Explorers program, a coeducational affiliate of the Boy Scouts of America that began 60 years ago, is training thousands of young people in skills used to confront terrorism, illegal immigration and escalating border violence — an intense ratcheting up of one of the group’s longtime missions to prepare youths for more traditional jobs as police officers and firefighters.

Searching for a terrorist, Explorers with the Visalia Police Department combed a building rigged with tripwire, alarms and "poison" gas.

I imagine the Visalia Police Department must have to deal with terrorists barricaded with tripwire, alarms, and poison gas often.
