then you're equally as full of shit, as you don't know either, yet want to allow them to come back without any recourse. If they want to come back, they can present themselves at the border and be questioned and scrutinised for what exactly they were up to. If they pass clean, they can go, if they don't, then they face the courts. Also, in this country, people are jailed for crimes they were complicit in or associated with, see:

So being actively associated with a group whilst they committed crimes against civilians could well be seen as something worth prosecuting. So no, I'm not full of shit, I think I've been perfectly reasonable. If they are simply allowed back through the border any of them (or none of them) could reasonably be assumed to pose a threat to society, so it is not unreasonable that if they want to return, they should go through thorough questioning and protective measures because of the sensitivity of what they've been involved with, and if they've done nothing wrong, and have nothing to hide, they can go home. Now that, despite what you want to protest, is not "full of shit", and neither am I.
