Waco is the defining cultural event of my life, couple with the fact that not only were the people responsible not held accountable to the law, but the people relected the President in 1996.
Neither Waco nor Bill Clinton's reelection was caused by any "broken" aspect of our constitutional system, unless you consider the people to be broken. It's an argument not without its merits. The system is reasonably intact. Oh sure, it could stand some serious improvement in its operation, and of course some laws are better than others, and certain judicial precedents are not exactly desirable. But my point remains: we had at our disposal several means of dealing with Waco and the aftermath of Waco. America freely chose. And likewise we have at our disposal all the power necessary to undo any bad precedent, punish any bad public officer, and advance any set of ideas we choose. I'd like to know why saying so scares you.
