Federal officials sought to portray a 37-year-old Minneapolis resident killed by Border Patrol agents on Saturday as a domestic terrorist, saying he wanted to "massacre" law enforcement, even as videos emerged that appeared to directly contradict their account. The man, Alex Jeffrey Pretti, was an intensive-care nurse described by the Minneapolis police chief as a U.S. citizen with no criminal record. Federal officials said he was armed, but there is no sign in videos analyzed by The New York Times that he pulled his weapon, or that agents even knew he had one until he was already pinned on the sidewalk.
