Listening to the pronouncements of many senior Police officers, you'd be forgiven for thinking that CCTV is a panacea for solving crimes.
At Big Brother Watch, we don't oppose CCTV per se, but rather it's ineffective nature. In our recent report, the Price is Wrong, we outlined numerous examples of the technology failing – or indeed simply not being turned on, despite being installed at a significant cost.
Sadly, it appears this problem is hampering the Police's efforts to find Joanna Yeates' killer.
"Fears are growing that the grainy images from Clifton Suspension Bridge in Bristol may allow Joanna’s killer to slip through the net.
"The bridge across the Avon Gorge is a notorious suicide spot and is scanned constantly by 32 CCTV cameras.
"It lies on the only direct route between Joanna’s home and the spot where her body was discovered.
"Detectives had hoped the cameras would provide a vital clue to help trap the killer but it is thought lights along the bridge at night make it impossible to identify grainy images of cars and pedestrians"
Let's all pray that poor CCTV footage hasn't let this killer slip away.
