There is an extremely blurry line between peaceful and violent protests. Unfortunately all of the chaos of recent days that the WaPo and others (Obama, etc.) seem all too eager to sweep under the rug has ruined things for everyone.
As someone said, maybe the right perspective is "it's too bad all this property is needlessly destroyed, but how can we let so many innocent people die, protestors get assaulted for no reason, journalists losing their eyes and being beaten and detained on american soil for doing their job?" Priorities my friend, says a lot about you. I am sure a country that can afford multi trillion dollar wars and bailouts can handle a few insured propertied burning down. Heck, some people might even profit with the right insurance.
If you hold the Federal Government responsible, then you want to put this power in the hands of Federal Legislature. Are you ready to forsake the federal structure of US Government?
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.
