apparently she's now sailing to Gaza (ETA 7 days), trying to break the blockade, with an 11-crew ship that includes herself and Liam Cunningham (actor of Davod Seaworth in GOT)?!?
I think this increases her prison chances, depending on whether things escalate

she was briefly detained and is now scheduled to be deported. based on this hebrew article, she and three others (not everyone) agreed to be deported; the others will be imprisoned (temporarily?). there's a picture of her on the plane, too.

Does being booked in jail count, or only if she's convicted of a crime and given a sentence?

@Jwags No, only by a sentence

@Jwags I’ll rephrase the question to ”sentenced to prison”
