Possibly greater powers to arrest people based on 'thought crimes' ie people with extremist views, people that sympathise with a terrorist cause, these should all be possible reasons to arrest/jail people. Sympathisers are well versed in what they can and cant say, they setup stalls irritating everyone (even muslims) with thier obvious intent, i dont think we should allow these people to engage, just imprison them & rehabilitate. The later maybe fairytale nonsense, but ofcourse we cant let these people free on our streets
