I’m afraid I don’t agree that John Mace’s commentary was something to drive the question into Great Debates territory.
When someone aks a question in GQ, the question carries with it some unstated but necessary assumptions.
For example, suppose someone asks, “Is it illegal to give a bottle of alcohol to someone you know is an alcoholic?”
Upon getting an answer that it isn’t, a poster might respond: “Well, what if he was arrested anyway, and what if the prosecutor and the judge and the jury all went along with finding him guilty?”
“Then he’d be released when the case was appealed.”
“But what if the appeals court also went along with it?”
“Then the state supreme court would overturn the verdict.”
“But what if they also went along with it?”
“Then he could file a federal habeas petition and the federal court would order his release as the act of getting imprisoned for a non-existent crime violates the Due Process Clause.”
“But what if the federal courts, all the way up to the Supreme Court, what if they ALL went along with it?”
At that point it’s pretty clear that the train has left the station, GQ-wise. It would be nonetheless relevant to ask, “Has there ever been any similar case?” because the inference is that, if there has not, there is no reason to suppose that all these thin ad-hoc assumptions have any realistic application to the question.
If you don’t, then you concede that GQ is meaningless, because any question can be answered a different way if we can continually add ad-hoc assumptions to refine it. “Can a person survive a 100-amp, 10,000 volt shock?” “No.” “But what if they were in the world of Pokemon, because Team Rocket routinely gets shocks that must be that big and they survive!”
Yes, but nothing in the original question suggested we were discussing the world of Pokemon. See the point?
Now, when you ask if the legal system would suddenly accept a dramatically novel theory of criminal liability, you basically move into the world of Pokemon. The original question (presumably) wanted to know about the real world and the realistic possibility of charging Bush with murder. If we assume that the legal system will suddenly begin working in a dramatically new fashion, then how can we possibly begin to answer any legal question? It can’t be done. But if we assume that the legal system will continue to operate as it has, then we may safely answer the question.
And for that reason, John Mace’s point is relevant to GQ. It’s never been done before. It’s never come close to being done before. There is no reason to suspect it would be done differently now.
