That kind of action is always a sign of panic that protests may gain more ground among ordinary people. The solution is MORE defiance, not less, just as the U.S. Injustice Department's war on parents is backfiring on a massive scale. Who among us would have predicted even 10 years ago that the FBI would be used to harass parents who organize protests against corrupt school boards bent on indoctrinating students with anti-family ideas and values.
So arrest them all and get the trucks get towed. Maybe it won't impact the supply chain. Maybe it will. Ford just idled 8 plants in the U.S., Canada, and Mexico due to supply chain issues. Not saying the Ottawa protest was part of it but it probably does not help.
