Yes and no. For the most part, the government works as designed. There are checks and balances and often times, either the legislative or executive branch attempts to go too far and that is where the Judicial system is there for to make sure it stays within the guardrails. And more often than not in our history, it has worked.
I don't understand your comments on the 4th amendment fully but if you are railing against the Patriot Act, I would agree with you that it is a violation. I said it on here in many posts many years ago and I maintain that position. I spoke up on here many times to hold those that favored it responsible and vote them out on that one issue alone. However, even if our government and our elected officials attempt to go too far, the citizens have no right to enact violence and do what they did yesterday. And the President inciting the violence was a direct conflict of his oath and is a violation of High Crimes and Misdemeanors.
