He's not protesting against the government.
Live by the state die by the state.
Again, it's hard for me to shed a tear for people who agitate for more of the beast that ends up devouring them.
Sure the police are wrong, and nothing excuses them or their masters who gave the orders.
But there's no good guys here. The protesters don't dislike the fact the power exists, they dislike they don't control the power. They were happy to use government guns to line the unions pockets when they could. They weren't protesting the government then.
