Police and FBI agents fatally shot whom they called a “terror suspect” yesterday morning outside a CVS pharmacy in a suburb of Boston. Twenty-six-year-old Usaama Rahim, who they say was under 24-hour surveillance and thus they wished to question him, reportedly was coming at them with a large knife, which prompted officers to take him down. Well, according to authorities, we now know what he was planning. Any guesses? Yep. A terrorist attack. Specifically, to behead police officers. And it looks like he had help. Because at least one other man, David Wright, was arrested just hours after the shooting, and is now in police custody, awaiting a Wednesday court appearance on federal charges. More from Fox News:
