There is a difference between security cameras and surveillance cameras. Surveillance cams are broadcasted somewhere else (maybe even over internet) and stored and reviewed. Security cameras - are for security incidents and shouldn't be broadcasted or footage stored longer than necessary (matter of hours or days depending on location).
Too bad often times these state owned security cameras are actually surveillance cams disguised as innocuous things which they aren't. There is this Will Smith movie "Enemy of the State", it's fiction but our dystopic society is becoming ever more scary.
I'm not sure what the bouncers are doing is right, either, though for some reason I'm more comfortable with it. (Which I find to be a really bad answer, frankly: is this just pushing my "comfort" of what I'm willing to put up with too far?)
This is like asking, what's wrong with state owned security cameras on the streets? It's digitizing what bystanders have been doing for centuries.
