No, that's not what I said. What I said is, if FBI wants it, it can be treated by them as terrorism, and to prove them wrong would take a lot of effort. And there's no way neither to prevent them from it, nor to punish them for getting it wrong.
And if you think matters are different in Canada with respect to how law enforcement works, or how "anti-terrorist law" works - you'll soon learn Canadian law enforcement can make one's life hell the same way FBI can.
