The army are not executioners.
If people are breaking the law, the government will stop them, via RCMP, local police, or even military if it gets really bad. Soldiers of Odin, Are they terrorists? They sound more like a bunch of thugs thinking they're some toughguy militia.
Nice thing about organized groups is you can break them up, infiltrate them, spy on them. Lone wolves are much, much harder to anticipate or stop.
