Look people, you can’t shoot him in the yard and you can’t shoot him on the porch in most states and you can’t shoot him the back running down the driveway. I hope the poor homeowner gets a decent jury.
As liberal as the State of Washington is, depending on the circumstances, all three of your scenarios (yard, porch, back) are justifiable shootings by a citizen. Of course - one takes the risk of not getting the circumstances just right, and also running into issues with a civil trial.
