well you;re right...these thugs all look at this as a game....and that with no concern for life nor body of others.
Their high school bullies that have never grown up and the way they keep their hair and clothes says it all.
My take on this? They are professional revolutionaries in training.
Medic is a cadre, hence he attends to injuries and is allowed to carry a sidearm. But training prohibits him from pointing it at someone or firing. He went in on shooter to grab his rifle. If he wanted the rifle why didn’t he use his pistol to disarm the kid after the kid shot skateboarder? Most likely not permitted to use his sidearm. So sidearms at this point are for defensive intimidation and control of Antifas.
This is their urban training period. Everything but live fire. They are learning their skills and organization in preparation for national revolt.
