Go with you instincts, but be realistic about your ability to fight off someone; your instinct may be to run, scream, kick, hit or bite.
If a weapon is displayed, don't resist. Give up your property and save your life.
Do what you are told and don't make any sudden moves.
Try to remember as many details as possible and alert Police as soon as possible.
Your goal should be to escape safety and survive; cooperate if you think that resisting may lead to further harm.
Remember every situation is different; you are the only one who can decide the appropriate course of action.
Constantly play the "what if" game to think about what you would do in a particular threatening situation. This will help prepare you to respond instinctively when a threat is encountered.
After an event, never feel guilty about what you did or did not do.
