Even though they orginated in the America the TCM has started to spread to the UK and some of Europe. The most famous incident involving the TCM was in America in the 90's which was delicatly named 'The High School Massacre' in which they stormed a high school, heavily armed, took the head teacher hostage and killed students and teachers. Also called the gothic movement.
