Wretchard at Belmont Club discusses advice from Dr. Ian Stephen for Brits whose home has been invaded by criminals. Hint: The advice includes this important tip:
Direct contact should be avoided whenever possible. If unavoidable, the victim should adopt a state of active passivity. In most cases the best form of defence is always avoidance. If this isn’t possible, act passively, be careful what you say or do and give up valuables without a struggle. This allows the victim to take charge of the situation, without the intruder’s awareness, through subtle and non-confrontational means.
I realize that different situations call for different reactions. But I do not believe I live in the world where this advice would be useful as standard policy.
