In this Nov. 25, 2014 file photo, police officers watch protesters as smoke fills the streets in Ferguson, Mo. after a grand jury's decision in the fatal shooting of Michael Brown. Newly released documents reveal that police planning for a grand jury announcement wanted Guard troops and armored Humvees stationed in the Ferguson neighborhood where Brown had been shot. But the records show the requests were not granted, because Missouri Gov. Jay Nixon preferred to use the Guard in a support role to police. (AP Photo/Charlie Riedel, File)
