Last year he was shot in the leg and he never got proper treatment. He was also unemployed and he was jealous of all those Palestinian Arabs who manage to get jobs doing nothing. Even though he was a long-standing member of the Popular Front for the Liberation of Palestine terror group, the pay was apparently not very good.
So he hatched a plan.
He kidnapped three American women aid workers who were in Nablus, called up the AP and said that he would release them in exchange for medical treatment and a job.
Nablus' district governor negotiated with Saud and they did what Arabs are famous for - they bargained.
In the end, Saud released the women. In exchange, he will get medical treatment and will not be prosecuted for the kidnapping.
