As runners start getting ready to head to the starting line in Hopkinton, hundreds of security personnel are already working to secure the marathon route.
Just inside walls of MEMA headquarters, hundreds of local, state, and federal officials are 30 feet underground keeping a close watch on the 122nd Boston Marathon route.
Last year public safety officers used drones and surveillance video from inside MEMA headquarters to keep an eye on the more than 30,000 runners and 1,000,000 spectators.
The agencies also keep in contact with plain clothes police officers above ground.
MEMA’s director told 22News in an interview last year that each agency has three jobs–monitor threats, coordinate responses, and communicate responses to more than 70 agencies.
Security at the marathon has been tighter than ever since the 2013 bombings.
MEMA said it’s a security response to make sure everyone has a fun, but safe Patriot’s Day.
