Or an anti gun neighbor walks by the gun owner’s trash barrels on trash day, throws a few empty beer bottles next to the empty ammo boxes and calls police.
"That would be a bit tricky to do, but I suppose if you want someone bad enough, and are sinister enough, you can find ways to get cops to do your bidding. It is a highly unlikely hypothetical, however."
Actually, that doesn't seem unlikely at all. With the current harassment and attacks on conservatives in restaurants, stores and HOA conflicts, a neighbor setting up another seems all too plausible.
