Who is being let go?
I think he/she meant that just because the guy is a bumbling idiot doesn't mean he should be released under the guise that this was somehow a set-up, as is implied in the story. I agree...he had a choice to participate or not, he made the wrong decision and should therefore be held accountable for his actions based on intent.
No one. Seems like your John P. Martin might be deeply saddened by that fact.
