One of the reasons that these stupid rules keep changing at different prisons seems to be when the security category of the prisons changes - which of course is little help to us.
Window dressing of a slightly more serious nature is the new restrictions around British and French nuclear sites. Much as I appreciate the sentiment behind it, I do not believe that a zone a few miles in diameter is going to give any protection at all from a B737 driven by a bunch of terrorists. I guess that the politicians need to be seen to be doing something, even if it is completely pointless.
In France the NOTAM suggests you are likely to be shot down without warning by SAMs
It should certainly concentrate the mind on accurate navigation !
