content: While I certainly agree that he should be tried and convicted before having these restrictions on him, this guy has clearly gone past angry rhetoric online and started towards making his way to the Middle East to join up with ISIS and start beheading "infidels". Read the article /u/Candlejake linked. He has produced an ebook detailing how other Western Muslims can avoid the security agencies and get to ISIS, which is illegal under Canadian law (traveling somewhere to join a terrorist organization is illegal) as well as stating outright that the violence, bloodshed and butchery displayed by ISIS can be a "good thing." This guy has clearly crossed a line from speech to action, so figuring out what actions to take to prevent him (and others like him) from carrying out an attack or something is a difficult one. I certainly don't believe in pre-crime or locking someone up for their thoughts or speech, but is there a point where we should take reasonable precautions with someone like this who has begun acting on his extreme views? I don't know, it is a hard line to judge sometimes. I did find this paragraph kind of disgusting:  Harun’s original contributions to his Twitter feed include vocal and explicit support for the Islamic State struggle, advice about Internet security and encryption to avoid snoops, hackers and spies — a constant theme among the group’s sympathizers — and disparaging remarks about moderate Muslims.   The way the author wrote it kind of paints anyone who is interested in Internet security and encryption as an ISIS sympathizer. That is a dangerous mindset that we need to speak out against if we want to preserve any kind of privacy in our communications.
