Flukin Bad Investigators aka FBI Boston are the same bunch that let Whitey Bulgar murder with impunity for decades, they are worthless as well as corrupt. FIRE THEM!
Maybe they cancelled when they found out these two guys are not involved...would make sense. I wondering about that that bearded guy with red shirt and backpack strap that matches the one that was detonated. The guy looked more out of place than the two gentlemen in question.
