Just as a side note, it appears that Dundee 'authorities' are not shy about about intruding on et privacy of law abiding citizens.
"Local authorities authorised 501 clandestine investigations into issues ranging from drugs and prostitution to dog fouling and underage sunbed use."
"The separate Regulation of Investigatory Powers Act ... allows Scottish authorities the additional power to trawl through communication traffic data such as phone calls, emails and website visits. Scottish councils often used these powers for investigations into serious crime related to drugs and prostitution, but the data - obtained through a series of coordinated freedom of information requests - shows other reasons for their use."
Fortunately UKP can covertly or not so covertly investigate which prossies are worth a shag and to be praised, and those which are just scumbags.
