AFRICANGLOBE - Contrary to what eye-witnesses claim – that they saw several snipers – Mr. Micah Xavier Johnson, 25, was singled out as the lone shooter and summarily detonated with a robotic device. Dallas cops claimed he was too dangerous to arrest. The Explosive Ordnance Squad in Dallas, which marshaled the robot to kill Mr. Johnson, has had access to a Northrop Grumman Remotec Andros F6A or F6B, a standard model for military use, for many years.
