This protest, I can get behind. The equivalence is much greater and they've targeted the people doing the surveillance.
I don't see anything wrong with this practice? It's just parking enforcement.
In my area, whenever a parking warden issues a ticket, they have to take photographs of the violation (the vehicle parked on yellow lines, expired ticket, etc.), of the ticket on the vehicle (stuck to the windscreen, under a wiper blade), showing the license plate, as well as the relevant parking signage.
Why do they do this? Because in the past motorists have tried every trick in the book to get out of fines. They weren't parked illegally, their ticket hadn't expired, they never received the fine, the signage was missing, obscured or incorrect.
It's a cat and mouse game, and if the last trick up the councils' sleeves is to record the parking infringement on video, then so be it.
No, it really isn't, and I'm not sure what motive there is to claim otherwise, especially as you clearly don't live here. It's been in trial/used in a few boroughs of larger towns, though in fact there have been a number of boroughs that have removed them after complaints (Richmond which is a London borough removed theirs in 2011, with the councilors themselves disliking them).
I've lived in London and a couple more large towns/cities over the last 4 years and have never seen one or heard of one being used in a local area.
'Course, we can all say what we have and haven't seen and go on for ages, without some hard stats.
I'm not really sure what they're supposed to do. You don't see them working late Friday / Saturday nights (the revellers just get a bit too rowdy around the delicate camera i suppose).
I should probably do a FOIA request and see what they achieve in my area.
We've had a few issues with covert cameras in parts of Birmingham. The latest on the story above is that the removal and disposal of the cameras will cost a further £300k on top of the £3m to fit.
Returning to the original article; in the UK, this guy would be having a conversation with the police rather quickly, especially if he appears to be targeting individuals.
