Apparently the police sniper
believed he saw the guy had a gun in his hand and was raising it towards other police officers.
Such things can happen. I remember back when Bill Clinton was president, one of our air patrols over Iraq massacred two US Army helicopters filled with civilian aid workers. Our fighter pilots believed they were seeing large Soviet attack helicopters preparing to slaughter Kurds on the ground.
It might be good (for both military and police, worldwide) if techniques could be developed to reduce the possibility of these sorts of erroneous beliefs. However, if such techniques were easily developed, they would already have been developed. Not an easy problem to solve.
