I checked the law before I came up with that position...

I can't legally shoot, but can legally point...

I'm basically betting that the BG doesn't read the state law, and assumes 'TV law' (i.e. that he can legally be shot for what he's doing)... If he knows I can't shoot him, it won't work... Basically, 'Do you feel lucky? (I hope not, 'cause I can't do anything if you do!)'

If the BG tries to shoot me, I have to attempt to withdraw (i.e. duck back into my house), and if BG's actions still threaten me despite said attempt (i.e. he then tries to break in, or he starts firing blindly at the wall), I re-gain my right to shoot... But we're back to the presumption that the BG doesn't feel lucky today...

As for open street encounters, the way WI handles things my gun is out of practical reach. The only scenario I can see where I'd use the glovebox gun are an attempted carjacking or armed robbery (with no option to run, i.e. stopped at a light with cars in front) that I 'see coming' in time to grab and load the gun. In that case, the 'death or great bodily harm' clause comes into play, and it's a different set of rules...

It is circular logic, but it's legally created circular logic (If they had prohibited the threat of deadly force as well as the use, this odd case would not exist. But they didn't)...
