The cop was NOT invited on the property, nor under any exigent circumstances in chasing a guy a selling meat from a truck.
Totally bogus shoot.
Maybe the cops should just come on your property and shoot your wife for barking at them?
If you don't want the letter carrier bothering your dogs just put a box on the street. Or, rent a post office box and go get it yourself every day.
However, when you place a mail box on your house you have INVITED the letter carrier to go up your path to the box.
Frankly, I think that's an antiquated way for delivering mail and should be eliminated, but legally speaking, the burden of any injury to the carrier is yours and the Postal Service will sue you for loss of his services while he recovers.
LOL!
