AM,
I hope but doubt it will work out like you think. The old man sees the kid, sneaks or charges up and grabs him around the neck. This hold lasts until the kid dies. There was no threat to the old boys life until he starts choking out the kid. Who then struggles until death.

We are not talking Forks or Republic here, we are talking Pugetropolis. The guy will not get that to fly IMO. We are looking at Man in the least.......Murder in the worst. Likely charged with premed and plead to Man2. If taken to trial......anyones guess what happens. Ten people dumb enough to not get out of jury duty can come back with anything from nothing to life.
