Re: Not only in America
This has happened in the UK too.
There was a successful lawsuit by someone who broke his back and hip trying to burgle a garage where the owner (quite deliberately) left the covers on the "service" canal a bit off to the side forming a nice 5m by 1m trapdoor.
In fact, the precedent base at present is - if there is the smallest suspicion that you have done it deliberately setting up "burglar punishment facilities", then you are at fault.
