No, I do not believe that JB and CC, who was pregnant for a good half of her captivity, mounted a three day resistance against their captors in which they took over parts of the compound. Presumably with 1-3 very young children in tow. I'll buy JB making a desperate, totally ineffectual attempt to go at a captor with a knife, but that's about it. I also don't understand why the Haqqanis would give two straws about whether or not JB joined them. The family's value was as potential bargaining chips, not as potential fighters. If there's a grain of truth in this, my guess is it has more to do with them wanting something they knew or believed JB might know about rival militant groups based on connections from his first marriage.
I do tend to think both that the kidnapping really was unconnected to Zaynab Khadar, and that both of them were actually captives; whatever abuse JB might have perpetrated on CC during their imprisonment, IMO, was separate from whatever the captors were doing to them. I also think he probably went to Afghanistan with ideas of meeting up with, if not joining, the Taliban. But based on the earlier article, it sounds like them getting kidnapped was actually a pretty predictable result of two Westerners walking into a dangerous area and shouting about their movements and intentions for everyone to hear.
Does anyone know what a typical sentence is for someone convicted on the kind of charges JB is being held on? I'm not asking for sentencing guidelines, since those are clearly going to yield a pretty hefty potential sentence if you add up the max for fifteen charges, but wondering what actually winds up being a typical outcome for someone held on a number of counts of DV including assault and sexual assault.
