i personally dont agree with defense of property as justification for killing intruders. is there a statue in MN law for killing intruders as a defense of one’s own life?

not exactly accurate

Minnesota is a duty to retreat state, but that doesn't apply to occupied buildings.
A store owner inside his own property has no duty to retreat and can legally claim self defense as a justification to kill someone threatening his life
but that doesn't apply out of a threat solely to property

if the pawn shop owner saw violent looters swarming him and reasonably felt afraid for his life, he has a valid self defense argument in minnesota.

Defense of life or the life of another is justified use of deadly force (where a reasonable expectation of great harm is present - that birder in Central Park would not have been justified in shooting Amy Cooper, as far as that statute is concerned).

Yeah, defense of life is the key. If there are looters inside, but you have no reasonable expectation of great harm to you or another from their actions, then it would not be justification to shoot them. That's a pretty blurry line though, regarding people inside the structure with you or others.

I'm saying that it is highly unlikely that a Target manager made a career ending move like this.

You're taking the word of rioters who are currently on a crime spree like few others. Rape, murder, theft, to say that your belief in them is ambitious is an understatement.

okay thats a good reasonable statue. i’d say a large group smashing your windows in violently could reasonably be aruged as a reasonable expectation of great harm. but im no lawyer

we can definitely rule out Amy Klobuchar as Biden's VP
that's a double dose of black support baggage, BLM would revolt

There's a better case for it there, for sure. If you're inside the building, but are holed up in a room out of sight from looters, and none of them make any overtly hostile moves in your direction, then that's much harder to justify self defense.

Imagine caring that Target gets looted.

Not news to those of us who have lived here for years (other than anything specific related to Chauvin). She and Mike Freeman, her successor in the DA's office, both gave MPD a pass on a great amount of misconduct.
