men have a little blue pill in the bedroom. are women about to get a boost of their own? "nightly news" begins now. good evening, we start here with a deadly confrontation outside boston between law enforcement and a man they feared might be preparing to launch an isis inspired attack. that man who police and federal agents had gone to question is dead shot they say after he came at them. authorities tonight still on the move in the boston area trying to piece together what he may have been involved with and whether others might be connected to it. our pete williams has late details. >> just after 7:00 a.m. officials say, a boston police officer and an fbi agent approached a man they wanted to question in a terrorism investigation. when they say he drew this knife, came at them and refused to drop it. >> we saw the video, and it appears that

the officers were backing away before they exercised deadly force. >> the man was identified as a man from the roslindale section of boston he had been under investigation for weeks. >> the subject had been under 24 hour surveillance. this investigation has been working side by side from minute one, including boston police department. >> officials tell nbc news they were concerned rahim had become radicalized and was actively considering an attack on police officers in boston within the next few days in a city still traumatized by the terrorist bombings of the 2013 boston marathon. they had no warrant for his arrest they wanted to question him, fearing he was preparing to take action soon. >> obviously there was enough information that we thought it was appropriate to question him about his doings today. >> his brother, a former boston area

imam said the family is grieving but wrote rahim was shot in the back three times while talking to his father on the phone saying i can't breathe. but police say he was shot twice in the abdomen and torso, not in the back. police and federal agents searched his roslindale home today. another address in the boston suburbs and in rhode island. officials say they're investigating whether rahim was in touch with others who may have been radicalized by isis inspired propaganda. officials believe they have disrupted a potential terror plot. now they're detaining other people for questioning. them they say rahim was in touch with to see if anyone else was involved with his plot or whether other attacks were planned. >> pete williams in our washington newsroom tonight. thanks. >> we're learning details this evening, about the fbi secretive airborne surveillance program, centered on a fleet of ordinary looking planes with extraordinary capabilities. including the ability to lock on to your cell phone.

stephanie gosk has been looking into it. >> fbi investigations often rely on surveillance to find criminals or catch them in the act. but what many may not realize is how often that surveillance comes from the sky. >> an associated press investigation found that the fbi controls a fleet of planes mounted with sophisticated video cameras and often cell phone tracking devices called cell phone simulators. >> they force every phone within their range to send back identifying information. >> the plane, possibly more than 100 are registered using fake companies. the ap identified at least 13. the fbi flew above 30 cities in 11 states in just one month. this plane with a camera underneath was used to conduct surveillance over baltimore this spring. after riots broke out over freddie gray's death. flight radar 24 tracked the plane's

route circling the city. they have been conducting surveillance from the air for years, it's easier than from the ground and it's done legally. fake aviation companies are created to protect pilots. civil lick erts groups openly question whether current laws reflect new and invasive technology. at a time when the public is openly debating what surveillance powers the government should have. the fbi's program is creating even more concern. stephanie goszk, nbc news new york. the senate ended a battle over programs that were halted when the patriot act buyered sunday night. the senate passed the freedom act which restores and overhauls powers under the patriot act that will allow americans phone records to be collected again. but under this bill, telecom companies will hold the records and the government needs court approval to see them. there were new
