“Easy prey.”
I once had a nice long conversation at my front door with a cop who had the wrong address. He never suspected that the hand he couldn’t see had a .44 magnum in it.
True, but he scenario is different.
An alert Freeper is more likely to be aware of an officer’s presence on his property than the average law-abiding non-Freeper.
The gentleman and his fiancee were not aware of the intruder until their dog lay dying.
