Terrorists who are part of a network have an exit plan available---safe houses, a means of being transported out of the area or out of the country, stuff like that. These guys' exit plan? Go home to Cambridge and wait to be identified, then panic and steal a car to try to get away, and toss home made explosives to try to throw the cops off their tail. When that fails, one dies in a hail of bullets, and the other's idea of hiding out is run into a back yard, cut the shrink wrap on a boat, and climb in, leaving a smear of blood along the hull.
Yup, those were two well-trained pros.
