Turns out that the trucks, that move everything, and the drivers are more powerful than the threat of using guns. All the truckers need to do is just park their rigs.
As the Good Witch said “You’ve had this power all along”.
The beauty of a very large truck protest is that LEOs can say “Move your truck else you will be ticked and towed...” but they have to start at the very beginning or the very end. End doesn’t work on a one way road. And waiting for each at the front to clear takes a lot of time.
