Some predators think people with disabilities are the easiest victims of all.
Some predators have a surprise in store.
Taijutsu instructor Jeffrey Prather simulates an attack with a crowbar. P.J. Dixon traps Prather's arm with his chin and his foot with his wheelchair. The attacker, experiencing pain in three spots, will either loosen his grip and lose his balance, or get a broken arm. For the latter, the chin and head are weapons, as are the teeth and the wheelchair itself. Almost all self-defense courses draw on the Asian martial arts, all of which combine psychological, spiritual and physical lessons.
