Heavy Security In Boston Today

The Boston Globe reports:

Boston will be largely open for business on Tuesday, but so much will be different, as a wounded city awakens to higher security and heightened vigilance following the deadly bombings at the Boston Marathon. Heavily armed police will be out in force. Bags will be searched on the ­MBTA. And the area around Copley Square will remain a crime scene, closed to the public.

Not since the Sept. 11 attacks has Boston witnessed such a show of martial power coupled with a sense of vulnerability and grief. The scores of rifle-wielding state troopers, National Guard members in fatigues, and municipal SWAT teams who descended on the city Monday will continue to patrol on Tuesday, particularly around the finish line of the marathon in the Back Bay.

Subway commuters are told to expect bag checks and delays.
