from the article:

"The FBI said the suspect attacked the agents and two Massachusetts State Police Troopers as well as other law enforcement agents"

translation: "so he attacked me, my partner, then he attacked those two state troopers, and then he attacked those other officers. it was a bloodbath until. well, between the 6 of us that I mentioned were attacked by this guy with a knife. We finally realized all of us were weilding guns and put an end to it. but only after he attacked all 6 of us, you see?"
