Nuclear scientist among held Hizbut Tahrir activists

Re: Nuclear scientist among held Hizbut Tahrir activists

Being a Islamist in not a crime in Pakistan but Hizb Tahrir is a banned organization in Pakistan (for good reasons). By holding a public rally, organizing meetings etc. these guys have broken the law in a very public way and challenged the state. Hence the arrest. Why don't they and there supporters file a petition with the, now free, supreme court of Pakistan?
