Bay State residents can expect the massive security surge prompted by the marathon bombing to continue throughout the week, with Copley Square under lockdown, the Common converted into a National Guard staging area and a flood of law enforcement officials patrolling Boston — even as city officials urged residents to return to work as normal.
“The city of Boston will be open, but it will not be business as usual,” said Gov. Deval Patrick, later adding that life in the city is “not going to be easy, simple or regular.”
Patrick said the National Guard has secured a 15-block crime scene and is limiting access in the area, and the Federal Bureau of Investigation has taken over the probe into who planted the explosives.
“There will be a heightened law enforcement presence. People should expect delays,” he said.
