Security at the Trade Center, as the Police Dept. Sees It Contrary to "With Security, Trade Center Faces New Isolation" (front page, May 17), illustrated with a photograph of construction barbed wire that will be long gone, the World Trade Center's campus security plan doesn't isolate the trade center from the Lower Manhattan community. Pedestrians and bicyclists will be able to enter the site and travel its streets and sidewalks as never before. Taxis, cars and tour buses having business at the site will have access after screening to guard against the threat of a vehicle bomb. Yes, delivery trucks will be diverted for separate screening, a reasonable precaution after the 1993 truck bombing of the World Trade Center claimed six lives and caused a thousand additional casualties. You make only passing reference to the trade center's destruction on 9/11, none whatsoever to the 1993 bombing, and mention neither the memorial there for the nearly 3,000 dead on 9/11 nor its requisite security. Nor do you mention that New York City has continued to be the target of multiple terrorist plots over the last decade. All these were important considerations in the balance of safety and access that we believe has been artfully achieved with the plan. PAUL J. BROWNE Deputy Commissioner Public Information New York Police Department New York, May 18, 2013
