To practice using available weapons, imagine you are suddenly ambushed. Give yourself only three seconds to get a "weapon" or "barrier" in your hands, with the emotional readiness to use it. Simultaneously be aware of and start maneuvering toward an exit or escape route.
Never allow yourself to be tied up or taken to a secondary crime scene
At a second, more isolated location, an assailant will have far more control over you. Go ballistic—immediately! Attack like a lioness and fight like you life depended on it, for it may.
Never give up
Another opening or stroke of luck may present itself. No matter the injury, if you are alive, you are not dead yet.
