The death penalty inflicted certainly can, which is what those of us with respect for human life are saying here. The question has already been posed and ignored but again, why would you blow the kid away instead of either (a) announcing you have a gun on him or (b) firing a warning shot?
Specious reasoning is making up strawmen because you can't defend your own sorry position.
A homeowner can do that, however they are under no obligation to do that in their own home, or should they be required to do it. All you are doing is placing the homeowner at a disadvantage if the intruder is actually armed, which was an unknown at the time this guy shot the intruder.
This all could have been avoided if he stayed out of the garage, and you refuse to admit that, instead blaming the actual victim here, the homeowner.
