why any Qaddafi exile deal will probably stumble

1358: Libyan rebels have asked Col Gaddafi to “stop the aerial bombing and leave within 72 hours” in order to consider any deal, National Transitional Council leader Mustafa Abdul Jalil tells al-Jazeera. In return they guarantee that the leader would not be “legally pursued on the domestic front”.

The word “domestic” is the reason. I’m assuming he would want international immunity, which the rebels are in no position to give, and I’m not sure which international body would be able to grant immunity after the word “genocide” was being used.
