It's not enough to fight terrorism and creeping Sharia/Islamic supremacism/imperialism. We must fight domestic criminals as well. Besides, it's no secret that criminal organizations have been doing business with terrorist organizations, making for an extra difficult job of cracking down on both.
Criminal organizations are not protected by the Constitution Act, nor by the Charter of Rights and Freedoms, plus a case can reasonably be made, as allowed by the Charter, that one can be forbidden by law from belonging to a criminal organization. And prosecuted under the law for simply belonging to a known criminal organization, which is what's really needed to really crack down, meaning we must, yes, throw criminal gangsters in jail (although simple membership ought not lead to lengthy sentences, unless evidence of actual criminal conduct/conspiracy therein is provided to the courts) just for being criminal gangsters. Why not? Leftists believe we can take rights away from (via "human rights commissions") folks who simply express views inconvenient to the Left's agenda, so...
