To try to run away is surely giving an assailant an advantage? At least, this is what we were always taught in martial arts training. Surely we aren't asked by law to try to run away before turning around and whacking him with the poker?
'Get in the first deadly blow' is what you are taught in the military, from what I gather from discussions with military men.
Of course, if the burglar isn't armed at all (pretty unlikely), then you can calmly sit down with him on the business end of your Kalashnikov, and get him to tell you his interesting story.....
Quite right,never turn your back on your opponent and never give up your weapons. Theres no honour -or point- in dying running away.
