The fleeing felon ‘rule’ is that a felon can be dealt lethal force if they’ve committed a felony such as murder and still pose a threat to the community. He was still armed ergo the defender is clear in his judicious use of force.
Any DA that even tries to go after him would be strung up by their nuts.
I don’t care what you guys think.
A Vigilante cannot shoot kelley sitting in a Mcdonalds eating a hamburger just because he just killed 50 people. If he is sitting there waving around a gun that would be a different story
Laying on the side of the road dying with no action on his behalf...you can’t walk up and execute him.
Sitting in a car dying...depends on circumstances

Prudent man rule would be easy in court:
Prosecutor: "Why, Mr. Plumber did you chase down the alleged shooter and kill him as he fled?! He was obviously not a threat anymore since he left".
Mr. Plumber: "I killed him because I thought that if I didn't he would be an imminent danger to society. Case in point, he just shot up a church. I thought that if he was going to do that, maybe he's on the way to shoot up YOUR church Mr. Prosecutor".
Judge/Jury: "Not Guilty. Case dismissed. Prosecutor, will you please step back into my chambers? "
