You got Waco right, it was their finest hour in recent history.
The Klintons thought that the Rangers were the Texas equivalent of the Arkansas State Police and that they would just clean the place up and leave. They had *no* clue about what the Rangers are or what they do.
Ooops.
If Earle asks the Klintons what to do, I suspect we will then find out if they learned anything after Waco.
