Going off-topic like everybody else..... I have been a member of TBN for 10yrs. It is the most useful rural forum I have come across. Descriptions of things is a bit of a difficulty, I have learned a wee bit of what folks mean, but I am still frequently baffled by what you folks call some things.
I still visit the English Farmer's Weekly site for UK related news/info, but a recent enormous refurbishment has resulted in the handful of regular posters diminishing still further. It was not broke, but somebody had to try to fix it - and failed.
Back on topic, I would not be too quick to blame the PI. He was probably told that somebody was taking water that had not been paid for, so his job was simply to find out who. Innocent until proven guilty, just the same as Tom Selleck. The supposed theft was widely reported, but this is the first mention of his innocence I have seen.
