Okay, ignore the protest part for a moment and look at the crime…
A group conspire to intentionally disrupt a major highway, breaking multiple violations including endangerment of motorists, major disruption of public and emergency services, and recruitment of 45 others to aid the intent, causing~ $3M in damages. And, yes, people of the publiic obviously sustained injuries but there is fortunately no known causation of death. This for 4 days resulting in over 700,000 people impacted and an estimated loss of 50,000 hours to the public.
Now that could be for whatever reason. The Tories, MAGA supporters, West Ham losing, or YouTubers; doesn’t matter. The law shows no bias or care and these actions, especially the conspiring and collusion, are certainly multi-year crimes.
