We will see what the court says starting with the initial pre-trial conference on May 6, 2022. As noted by the DA -- the law is very clear on this matter -- deliberately blocking someone on the road for hours is a felony.
It's not like these protestors had a parade permit, road construction permit, or any other legal document which allowed them to block traffic for hours thus falsely imprisoning people by refusing to let them go by. If the protestors actually allowed cars to pass -- thus not falsely imprisoning people -- then they would not be indicted on felony charges
Now if the drivers actually drove over the protestors (who are in the middle of committing the felony of false imprisonment) then you would be moaning loudly what terrible people the drivers are and how they need to be indicted for doing nothing more than freeing themselves from being falsely imprisoned by felonious criminals.
