In some countries, like Sweden [1], this type of deployments of cameras are strictly regulated. A quick reading of the rules in Sweden tells me that you are unlikely to get permission for this easily.
Sure, but I would bet money that GP isn't in a country that has those kinds of regulations. I'm addressing their emotional overreaction to something that require rational action (such as the law you mention).
What exactly are you going to call the cops for let alone sue for?
While I don't agree with this kind of technology you seem to be overly emotional about it which really doesn't help the issue.
