I think it's not the worst thing in the world for there to be visual elements inspired by the 2nd Amendment. If nothing else, it puts pressure on the government and shows that many free thinkers have solidarity with Canadians.
In Canadian terms it's politically one of the most foolish things you could do. There's little constituency for 2nd Amendment style gun rights in Canada, so they'd be sawing off the limb they're sitting on. And that's apart from whether they broke the law, which would also be politically foolish since it undermines their argument of civil disobedience. I don't know anything about the facts of this case though.
The point is that many other countries should adopt rights similar to the 2nd Amendment, because it has been proven to increase civil liberties with very few downsides. Canadians who refuse to do so are more likely to be trampled by big government.
