Ultimately, who is causing the blockage? If everyone stuck to the law, and drove safely, would there be:
- more blockages, or
- less blockages?
Of course there would be fewer blockages.
So what?
The fact they are driving like idiots and breaking the law does NOT excuse somebody else deliberately blocking the road.
I am not in any way excusing the behaviour of those he targets. As I have already said, he is absolutely right to video them, and to report them to the police.
But vigilante action is hardly ever right, and that is what his actions by blocking them are.
