The question isn't whether there exists some other scenario would justify violently resisting law enforcement. Sure, the Warsaw Ghetto uprising was justified even if the Nazi occupiers were acting within the bounds of German laws at the time. But that's irrelevant. The question is whether this scenario warrants it.

And like it or not, countries have the freedom to define their own immigration policy. If I overstay my tourist visa in Canada I'll get deported. This isn't some grave violation of human rights.

If someone decided to open fire on Canadian immigration enforcement officers to try and block my deportation, they should get prosecuted and imprisoned.

Your persistence in trying to justify shooting law enforcement is disturbing. It mirrors the thinking that motivated January 6th rioters beating up the police. Like you, they believed their mission was righteous and justified violence against law enforcement.
