(Portland, OR)  --  Portland Police Chief Danielle Outlaw is defending police tactics that allegedly seriously injured three people during Saturday's alt-right rally and counter-protest.  Outlaw spoke at a news conference Monday saying officers were successful in preventing the rally from becoming as rowdy as it was expected to be because of the tactics they used.  Outlaw added that the Police Bureau would temporarily stop using flash-bang projectiles.  The Oregonian reports three people were hospitalized after being struck by crowd-control munitions fired by police at the rally.  One woman tells the Oregonian that a flash-bang grenade struck her friend in the back of his head and lodged itself into his helmet.  A nurse reportedly told the man that the blow would have killed him if he hadn't been wearing the helmet.
