Many thanks for the links, Laz.
I've just read through the UK version and, whilst it contains a lot of useful information, I think it would be better titled, "Restrictions on Photographers in the UK". Very well worth reading, but probably not suitable for showing to over-zealous security staff or irate members of the public.
It's probably also worth pointing out that this year (since the article was written) there has been a general upsurge in paranoia related to photography for the purposes of pedophilia. Amateur Photographer has run several stories on this.
A UK Photographers' equivalent of the ACLU Bust Card (also dealing with landowners, security guards and paranoid parents) would be most welcome, if anyone with sufficient legal acumen could put one together.
This seems close, although it doesn't cover quite everything.
