when is it "ok"?

Ever hear the phrase,
"It's not the size of the man in the fight...It's the size of the fight in the man."
A 100 lb. woman can do a lot of damage if she wants too.

If someone were to come into my house in the dark unwelcomed I would tell them to stop and identify themself and if I didn't get an answer then I would give them a blast with my flashlight. The best thing you can do is ruin their night vision.
If I identified them as a threat wether it be they were carrying a weapon or there body posture told me they were up to no good I would take them out. Then I would call the police and then call my lawyer.
