I was a student in Cambridge, MA in the winter of 1978. Eastern Massachusetts had a huricane level snow storm that shut down the City of Boston and the surrounding environs for a week.
Since there were no classes, a few buddies and I got on the MASS Pike west, and skiied in Vermont as things cleared up.
When we got back, the area was still closed, and what I remember are police and national guards carrying rifles in their trucks, dressed in fatigues. Scared the hell out of me. It was a snowstorm, not Marshall Law.
I do not diminish how awful what transpired in Boston on April 15 is. Some photos I saw Tuesday morning had sworn officers with rifles and high powered weapons walking around the crime scene in Back Bay. It reminded me of my 1978 experience, and I express my reservations that such a display of force is called for. Especially in an area that rightly is sealed off.
