What confusion? There was no reason for “confusion” at that house. All was quiet until the cop went onto the property with gun drawn and yelling. Like he couldn’t have knocked on the door like a civilized person or waited patiently until the owner came out and put the dog away. Geez, dogs bark. That’s what they do, especially if someone comes on the property yelling and threatening their owners.
I didn't write the "confusion reigned" comment, that was a comment upthread from Paine in the Neck, not sam_paine, (the other pain in the neck.)
But you know the answer to your question. There is confusion at that house because the resident assumed he was a free citizen and the cop assumes he's the ultimate dictator on a power trip. Hence the confusion.
