Massive 20-ton sanitation trucks, weighted with an extra 15 tons of sand, will surround the iconic New Year’s Eve celebration in Times Square, officials said Thursday, describing a security measure meant to stop deadly truck-driving attacks into crowds like those in Germany and France. The placement of the 65 trucks, along with 100 patrol cars, at intersections surrounding Times Square is a new element to an already heavily policed event that will include 7,000 officers, specially armed counterterrorism units and bomb-sniffing dogs.
