In 2002, the BBC reported that the average Londoner is caught on CCTV cameras 300 times a day. London alone has almost 7,500 council-operated cameras and many thousands of private cameras which are often of a higher definition than a digital SLR. But all this is nothing compared to the power of the smartphone.
The ubiquity of a rolling smartphone camera has turned crime-fighting into a social event, as the investigators of the Boston marathon bombings have proved. Police took a “tremendous” amount of video footage from members of the public who were in the area around the time the bombs went off. And now…they have a result.
