The BLM guys did this in Santa Cruz, Calif. about 7 months ago.
In that case, they interlinked arms inside of heavy iron piping that transitted garbage cans filled with concrete.
The Highway Patrol had to clear it —taking many hours— and there was no violence.
The catch was that some very influential, rich tech people had been hugely delayed and they later brought legal resources to bear —tort suits.
The hurt put on those dirt-head lefties was not physical but on the legal level it was very extreme.
We heard very many follow-up stories on the radio about those suits. It seems like they really sicced a really expensive Lawyer Party on their a$$es.
Well at least somebody is fighting back. Good.
Any further details? Couldn’t find on a google search. Sounds like a very interesting avenue: protestors commit tort, get sued mercilessly.
Now, you’re talking!
