Hoping to gain some tips overseas, Mayor Bloomberg will stop in London next week to observe the city's security camera network. He was already heading to Berlin to accept the 2010 Henry A. Kissinger Prize. London's "ring of steel" network of cameras were the original inspiration for a 3,000 currently being installed in lower Manhattan, and for one planned for Midtown, which could help in response time for incidents like last week's Times Square bomb scare. However, the city should probably work on getting the existing camera system working before trying out any new surveillance plans.
