If they truly suspected she was dangerous why would they have let her keep her hard drive? From a security standpoint that's just dangerous. And the whole decision to just shoot her laptop because it allegedly posed a threat makes no sense at all, as others have pointed out here. No, this was all about punishing her for living in an Arab country and showing what looked like too much interest in or sympathy for Palestinians. This was all about intimidation and repression. An American non-Jew, I was raised to admire Israel and support its existence as the only democracy in the Middle East, but over the past few decades I have watched the dream of Israeli democracy die as Israel becomes gradually more authoritarian, brutal, and corrupt.
