Authorities Test Olympic Security for London Games
Olympic security officials said that testing is underway for the task of making the 2012 London Games safe -- trials that include testing body scan machines, communications equipment, response time and extra closed-circuit security cameras.
Testing events have already begun to allow security officials to gauge how well they're able to communicate between venues and Scotland Yard's headquarters, as well as how quickly they feed important data into a government system of dealing with potential crises, says an AP report.
