Only if the person in that position is CORRUPT. Ron Brown's Special Prosecutor showed what can be accomplished if the person is HONEST. Even with the rest of the administration trying to protect him, Brown was soon more than willing to talk ... so much so that it appears the Clinton adminstration had to silence him ... permanently.
Starr, on the other hand, was coopted from day one. He was the number 2 person on a list of people supplied by ... who else ... the Clintons for the position. Other than the Monica revelation, he discovered NOTHING. Klayman, with FAR less power, discovered more about Filegate and Chinagate. Starr failed miserably in following up the leads Klayman supplied in Filegate and completely WHITEWASHED the Foster case. And note that his whole investigation was shutting down ... when the Ron Brown matter started to heat up. Questions about Brown's death were actually starting to surface in the regular media. The black community was calling for an investigation ... an autopsy. Clinton knew he had to do SOMETHING to distract the media and there wasn't any WAR brewing that he could USE.
So ... out of the blue ... Starr "discovered" Monica and she became THE ONLY STORY. And, given the FBI files, Clinton KNEW that there wasn't ANY WAY the Senate would ever convict him. He KNEW that the Monica story could be spun. He knew that exposing his tryst with Monica was much preferable to having accusations of murder and TREASON levied against him and his administration.
And if you don't think Starr was dirty, then explain this. Why did Starr allow the Clintons to keep those FBI files in the Whitehouse FOR YEARS after he told everyone that it was ILLEGAL for the Whitehouse to have them? Why did he say NOTHING when the administration and the FBI told the public that the files had been returned? It's a simple question.
