DHS Agents Broke Alex Pretti's Rib A Week Before They Killed Him

DHS officers have been collecting personal information about protesters and "agitators" in Minneapolis, sources told CNN – and had documented details about Alex Pretti before he was shot to death Saturday.

Sources told CNN that about a week before his death, DHS agents broke his rib after they tackled him for trying to protect a family they were pursuing on foot.

DHS law enforcement claims to have "no record of this incident.”

Did they know who he was when they killed him?
