Shooting to protect property, and not life, is usually an iffy situation, at best.
So true, in MN this is a no go. If a guy is walking out with your 50" plasma TV, you gotta let him go. If you can claim you felt you or your families lives were threatened, now you can use deadly force (although if his hands are full with your TV then that might be hard to do). So bottom line is if it's happening outside your house, you don't begin to be able to justify a shooting.
Sadly in today's society so often the rights of the criminals out way the rights of the victims.
