...Doesn't this differ from Oklahoma's stance if on your own property?
Here the act of breaking and entering is proof enough. That being said, shooting at fleeing suspects should not be done. Of course shots in the back happen all of the time due to a criminal turning at the last second. I would suspect there would have to be significant evidence that the homeowner was shooting a fleeing suspect before a DA would prosecute. Most juries would side with the homeowner, so a DA would not try a weak case.
