[toast0]

Ignoring the question of if it's unlawful or not; mass arrests are kind of difficult to do, and mass towing is kind of difficult to do (and I don't know if tow truck drivers are aligned with those in the convoy, but they might be?). Neither of these things are without consequences, either. As long as the protesters are mostly peaceful and respecting property (which I think seems to be the case, but I haven't spent a lot of time looking into this), encouraging the group to disperse without use of force would probably have better outcomes than escalating the conflict with arrests or towing.
