Although the NYPD has always staffed Summer Streets, Eckerson said far more officers had been deployed to this year’s event. Another Summer Streets event in Manhattan is set for this Saturday. Brad Weekes, a police spokesperson, said the security measures at Summer Streets came in response to terrorists driving into large crowds in other parts of the world. “This was an operational decision intended to ensure that people could enjoy Summer Streets safely.” Attendees noted police used vehicles to create choke points throughout the Summer Streets route.
