With no experience of this sort of thing whatsoever, but with the way I feel about burglars and similar, I'd say I'd have no problem shooting the guy dead. The knife definitely tips it that way for me. If I sense any sort of potential for harming me or mine, I would shoot, I'm certain. (PS. I've had knives pulled on me before in the street, so know how this feels, and I don't think I'd shoot someone for just pulling a knife - I would if it were in an isolated place with no chance of me getting help if I go down though)

However, until I've walked in your shoes, I have no idea what would really, really happen.
