Not much you can do except slow roll through them, if they stand in front of your car, let’s face it, you can’t run them over, unless they are attempting to break your windows or enter the vehicle, then you have the right to get out of the situation.
The best thing you can do is call your local officials and your congressmen and get them to get the police to enforce the law. They need to arrest these rioters for disturbing the peace and blocking the right of way and preventing people from their right to freedom of movement.
Apparently, people believe they have the right to protest wherever, whenever, and that they have the right to force others to listen to their protest. That is not the case. You have the right to peacefully assemble to petition the government. some would argue that to petition means literally to gather together to collect signature on a petition to submit to government for change.
Regardless, it means you can petition the government, meaning you can gather in a place near a government building and have your protest. It does not mean you can go into residential areas, into the streets, and disturb other people. Your right to protest does not mean you can force others to listen to your protest. You can’t get up in their faces, assault them in restaurants, block traffic, take over freeways etc.
It’s time the police enforce this to keep people them from interfering in other people’s lives.
