You can go play with sharks in shallow water and try to engage with them just like the woman from Canada but you can't blame the shark when it bites both your hands off, which it did.
Iran has history's of detention and bargaining using people as the chips, Nazanin ratcliffe was in the news and detained for 6 yrs, the regime is morally bankrupt and don't give a stuff what they do, if you choose to ignore a travel ban then unfortunately your at fault as the country was like that before you set off and they knew it and said the risk was outweighed by the gains, well that turned out not to be the case.
Hopefully they will take them to the border and say look we are a nice progressive regime, worst case is they trump up security charges and say they were spys.
