And this is part of what makes these hard to deal with -- it's possible even if everything's done right, feces occur. And 1) fixing the issues with the individuals, and 2) making it harder for ISIL to be attractive to some people with issues, are both hard to fix. Hell, I'm even having trouble asking the right, precise question for a solution.
Anyone interested in what buddy had to say for himself while the peace bond was being litigated, see attached TorStar Q&A from last year.
I'm looking forward to hearing more, but now, we have one case, here, in a western democracy where
it appears someone on a peace bond was still able to make things that go boom, and another case where
even being under surveillance (admittedly intermittent) didn't stop planning & execution of an attack.
I'm not a fan of preventive detention, but these show me surveillance alone doesn't seem to be enough.
