> Avoids data breach rules if you say it was "unauthorised access",
The computer misuse act defines "unauthorised" as including "in excess of authorisation"
I'd say slurping up details unrelated to the exact jobs in hand would qualify (and could also be used against anyone who looked up a celebrity's or ex's details on the police or NHS systems too)
This is why you must be very careful what you wish for. One of the "Wishlist" laws which is wending its way through the system at the moment is aiming to make simple trespass a criminal act. It's aimed at dealing with all the traveller incursions on private and council land but I can see it being widely abused against anyone that "security guards" in "public but not public" spaces (like most open spaces around urban London) don't like. It'd be even more ironic if it was used against a Hunt that traipsed across someone's land chasing their dogs after they'd got scent of a fox (this is a regular occurance in Surrey and landowners who are opposed to Hunts would do it in a heartbeat)
