Boston Marathon security stayed at high level

The city’s detailed security plan for the 117th running of the Boston Marathon shows the same all-out mobilization of officers, bomb-sniffing dogs and explosives specialists as was in place for last year’s race, an indication that the intensity of security preparedness has remained at a high pitch.

Interviews with law enforcement officials and a Globe review of Boston’s plan to police the race show that state and local authorities this year took extensive measures to protect hundreds of thousands of participants and spectators — including the deployment of air patrols, K-9 units, and more than 1,000 uniformed officers and soldiers along the 26-mile course and the finish line.
