One problem with cameras is that you can’t trust the watchers not to misuse them:

Two council CCTV camera operators have been jailed for spying on a naked woman in her own home.

Mark Summerton and Kevin Judge, from Sefton Council, Merseyside, trained a street camera into the woman’s flat.

The images from the camera, including the woman without her clothes on, were shown on a large plasma screen in the council’s CCTV control room in November 2004, Liverpool Crown Court heard.

Over several hours, she was filmed cuddling her boyfriend before undressing, using the toilet, having a bath and watching television dressed only in a towel.

Judge Gerald Clifton told the three men: “To dismiss what was happening as laddish behaviour, something that the 21st Century apparently condones, is absurd.

“You only have to read the impact statements of the lady to realise the harrowing effect that this had on her.

“Her life has almost been ruined, her self-confidence entirely destroyed by the thought that prying male eyes have entered her flat.”
