The spook was probably gonna die that night no matter if the cops showed or not. That's pretty obvious.
The fact that Chauvin coddled him and kept him safe in spite of himself until the medics could collect the corpse was a kindness uncommon to pigs. Back home they woulda just rightfully caved his head in and saved the county some money.
Seems like it's high time for all those northwoods dead eyes to show off their long game. Nothing puts the kabosh on a good ole lootin like a sniper or 3.
