Doherty says he remembers Caliguri telling himthat fighting against the bedlam in the Squareprovoked memories of combat in the war which hehad just left.

"He said that he couldn't believe he had comefrom Vietnam and that fighting over there to this,to the fighting right here in the city and townwhere he was born and brought up in," Dohertysays.

Asked if he resented the students forprotesting a war so many of his friends andcolleagues had fought in, Doherty says absolutelynot.

"Resent them? No. Why should I resent them?" hesays.

He explains, "A lot of the people I grew upwith at that time were all veterans. There were alot of people in that protest who were there andthey didn't know what they were there for. Theywere just being a part of it."

Unlike Caliguri, Doherty says he has not hadsecond thoughts about his participation on the"other side" of Harvard Square's student riots.

"I don't know who was right and who was wrong,"he says. "I'm a soldier and a police officer and Ido what I'm told.
