This is an oldish gem from Tuppenceworth from the Data Protection Commissioner's report. He received a complaint from people whose back garden was overlooked by LUAS CCTV cameras rather then remove the cameras

Connex (LUAS operators)then modified the system so that the camera /monitor was now showing a black screen when moving over the private property in its range. They also said that these settings cannot be changed by the personnel who are using the cameras and monitors in the Central Control Room of Connex.

Yeah, right, we believe you though some cynical types might be suspicious.
