"If the locations of these cameras were published" <people> "would know where they are, and could bypass/avoid them"
Potential criminals? What happened to being presumed innocent and all that legal malarkey?
I'd like a camera on my street and a big sign pointing it out. Then I'd like everyone to bypass and avoid my street, turning it into the safest street in Manchester. That would put the house prices up and I'd be quids in.
