>Well there are certainly exceptions to every rule and I think the crucial thing is that there be clear evidence of the threat of bodily harm. Usually that can only be proven to legal satisfaction if the intruders make it into the home. There is always the possibility the homeowner can evade the intruders by leaving the home himself (if possible and always the best choice). Two thugs kicking in the door of a senior citizen I think is ample evidence (unless it was relatives or neighbors concerned about his health and that obviously the case) of such a threat and fear.

Though a good deal is too strange to be believed, nothing is too strange to have happened.
- Thomas Hardy
Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm-- but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves.
-- T. S. Eliot
Democracy is two wolves and a sheep voting on what to have for lunch.
Liberty is a well-armed sheep contesting the vote.
- Ben Franklin
Pardon him, Theodotus. He is a barbarian, and thinks that the customs of his tribe and island are the laws of nature.
