"Active shooter" refers to any situation where one or more armed assailants set out on targeted or random attacks for the purpose of creating mayhem, rather than performing a robbery or holding hostages. December's horrific shooting in Connecticut is just the most recent example, though production began on "Lockdown" long before Adam Lanza took the lives of 20 children.
