Uh, what country is this in?.................
The key word is “fleeing”. If the robber(s) were outside when shot at then the guy is sunk. But, I suspect, the police questioned all parties and the perps said they were leaving because they heard him returning or maybe the homeowner admitted they were leaving, but, if one or both were still in the house, even with their backs to him, I think he could argue that they were merely seeking cover from him and were obviously armed themselves and he got the drop on them before they did on him.
Its NOT the America of Jefferson, Washington, Lincoln, or Adams. As a matter of fact, its not even the America of FDR, Teddy Roosevelt or Dwight Eisenhower.
WE are to blame for this. WE elect the gutless parasites who are responsible for turing our Country over to illegal invaders, criminals, and other lowlives while the “Legal” system has been turned into an illogical parlour game which benefits parasitical police, attorneys and courts.
