JessTheDog,
Theoretically you are right, however there are two major "get out's" and I'm afraid that they are self inflicted!
First, your Lords and Masters have voluntarily waived your rights for you, secondly, have a good read of your commissioning scroll and see just what you signed up to!
The New Fire Services Act and it's ilk are likely to keep a good few colleagues of mine in Ferrari's for a good year or two. The European Court of Human Right's is going to be a right royal battle ground over the next few decades.
