Do you not think there are laws everywhere about blocking traffic? When you reach a destination in your car, do you just park in the middle of the street?
I don't, but I think of it as normal, because commercial vehicles including delivery trucks do it all day every day in the area that I live in. They do it in the right lane of city streets that have two lanes each way, and they do it on streets where you have to cross over a double yellow to get around.
Aside from that, I have lived in the approximate center of a moderate sized city (metro area of ~1 million) and noticed that there are occasional, authorized events that take over and prevent any and all traffic. Bicycle races for instance.
Assuming one isn't vehemently against a protest in the first place, debating blocking traffic boils down to the technical requirements for permits and coordination with authorities. It's only a shocking breakdown of public order if people strongly oppose the underlying cause.
I'm asking you since you brought it up. And the question was not a hypothetical about someone parking in the middle of the street but specifics about what laws have specific people broken here.
