Ah yes. I had forgotten for a moment that this was Slashdot.
If you say so. "UK Gov't Launches 'Your Freedom' Website To Seek Laws Worth Repealing " may not be the most general of cases. I suppose a statement (by you) that "in the US federal la requires the possibility of..." would be very hard to argue with, as well as entirely informative. BUt what you said was that it is done fairly often. As I mentioned, I have read of it occurring in an Australian State, can you point to the laws you refer to being invoked or used in some specific case in the US? I do not think that these laws exist in the UK (where, BTW, I live) and am pleased to help anyone else avoid confusion on this.
I've seen one report of that occurring in an Australian state, none in the UK. Could you point to some of the "fairly often" cases you are citing, please?
