Re: Articulated responsibility.
"Be careful of the blade you use to cut through counter arguments, it may be the same one the other party uses to slit your throat."
One of the water authorities on this side of the Atlantic narrowly dodged such a blade when they tried to press ownership of rainwater being collected off of people's roofs. They started to argue that they owned and were responsible for all the water that fell out of the sky, in the streams and rivers and to the sea (and were quite strangely being egged on in these claims by the other side) before one of the company barristers realised that prevailing on that claim would be painting a big FAT target on them, turning the water company into a sitting duck for unlimited liability claims over flood damage, etc.
At that point the water companies quickly folded their tent, vacated all claims on rainwater collecting and got the hell out of the courtroom.
