It seems the low life gibsmedats got exactly what they were asking for...trouble. And Mr. Kim gave them an extra heaping helping of it. Too bad Kim might go to jail over this. He should have done it some day in the future...from a distance...with a hunting rifle.
Except he snapped. Sounds like like fecal litter when from inconsiderate negligence to the deliberate actions of purposefully piling it up on his front porch.
I like to wonder if as his neighbors found themselves looking down the barrel of Mr. Kim's Glock, their final thoughts were a brief moment of clarity, "maybe we shouldn't have done that."
