No, I most definately thought of that, but usually we'd be just as appalled as they are.
If we have reason to doubt that they could carry out the trial in a fair manner, or even that they don't have grounds and evidence to convict this person (or maybe it's false?), we should be able them out if we please.
I think the government doesn't like to not have power if something goes awry. Just because we allow going in there to get ther people out, doesn't mean it'd be something exercised much, or even at all.
