The democratic system is founded on the fundamnetal rights of the people (live,liberty and pursuit of happiness), the police are attacking these fundamental rights and the people are excercising their right to freely assemble and air their grievances to the government, and again they are being physically assaulted for it. Proteating is a democractic process as is journalism.
If it helps protect innocent people's rights, I am willing to forsake the federal structure of the us government. I would actually be in favor of rewriting the condtitution. I think you forget the american war of independence and civil war were fought over much less.
