RAD

Classes are held in community centers, YMCAs, on college campuses, and so on. My state alone has dozens of locations. Classes are also offered for children and for men. In Wilbraham, like most places, the course is conducted by police officers.
The first class is usually just discussion. Then it gets interesting. The next three classes involve practicing various self-defense strategies. The last class is the kicker. Instructors dress up in special RAD-man suits, designed to withstand moderate impact. The ladies are told they can give it all they've got. And apparently many of them do.
There are always some women who have been in actual bad situations before--abuse, assault, rape. It's easy for an experienced instructor to spot these victims, even if they don't speak up. Usually they find the last class difficult, if not downright traumatizing. The Wilbraham group always has a female officer on hand that night for support. Women are encouraged to work through their fear: otherwise, the aggressor has won.
RAD classes attract everybody from young girls accompanied by their mothers to elderly women living alone. They've got one thing in common besides their gender. After five weeks together, you wouldn't want to meet any one of them in a dark alley.
