The Posse Comitatus Act is a good and wise law. However, the laws can only be as good/bad as the persons charged with enforcing them.
In the case of the Waco massacre, the executive branch of government in charge of enforcing Posse Comitatus became the violators. We have a constitutional mechanism for dealing with this situtation and it is called impeachment. The congress and Senate failed to do their duty by letting clinton cop a plea for perjury. Then they failed to convict.
This is why character matters and a Westly Clark presidency with the fithly clintons running the democrap party would be disasterous for America.
That may be so but the potential exists for thousands of US citizens to be murdered by our own government before having to answer any charges.
It's my understanding that Posse Comitatus can only be suspended during a declared National emergency.
But then Clinton thought of himself as omnipotent and looking back, for all practical purposes, was.
