Stripped when walking down the street?

This is a report from the BBC about ‘virtual stipsearches’ that wer/are being considerd by the Home Office. The idea is to put them on things like lamp post, that way if you want to ‘virtualy strip search’ people, you can do so without them knowing.Whats the problem with this? The images are so detailed it is like someone taking a naked photo of you. These sort of images are already created in air-ports and some train stations, the only difference being they need to ask you first and you can take the far less intrusive pat down
