If all the truckers were armed, the jackbooted "just following orders" police would be a lot more hesitant to do anything. Remember when all those protests happened in Michigan a few weeks before St. Floyd of the Fentanyl Cross bit it? Whitmer wouldn't even consider using state violence because the risks were so high, as all the protesters were open carrying.
Just another reason to recognize that there is truly no place in the world that even scratches at the ideal of freedom except the United States. Sure, the US has got lots of problems, nobody can deny that. But in the end, we theoretically can't be deprived of life, liberty, or property without due process. It might take going to court a year or two later to hash it out, but that's still better than Canada where your kids can be taken away, your dogs killed, and your life destroyed, all without the least recourse in any avenue of life.
If we had a smart president who actually cared about working people, we'd be offering political asylum to Canadians on the basis of them escaping from tyranny. Good way to alleviate some supply chain problems, too.
