offhand the articles mentions: "She added that she had also been carrying an Arabic phrasebook, stamps from Syria, Qatar and the UAE and a Palestinians in Palestine guidebook." No wonder they found her suspicious as she fit the profile of a girlfriend working for Arabs against Israel or a ISM agent. I'd be upset if someone shot my Mac book and I wonder if she cannot apply for compensation as that seems to be unnecessary that if it was really a threat they could have held on to it and checked it. Perhaps the computer had something offensive in it against Israel?
