According to news reports, Kelley, who was given a dishonorable discharge, a twelve-month confinement and a reduction in rank x 2, to basic airman, for assaulting his wife and child, dropped his weapon at the scene of the crime.
He made off at 95 mph (kph?) with two local citizens in hot pursuit, including a 'Johnnie Langendorff', who said he stayed in contact with police during the chase.
Kelley veered off the road into a ditch, Langendorff took aim, even though he wasn't sure whether Kelley was conscious, or not, and shot him dead.
He is being hailed as a 'hero'.
But is vigilantism heroic, when the danger had passed and the perpetrator had dropped his weapon?
Well, maybe it will be argued it was 'justifiable homicide', but far better IMV would have been to take Kelley to trial and death row, the proper way.
