Yes.
Clinton had the FBI take over the TWA800 disaster within minutes of it occurring,and had the FAA stand aside.
But, he had the FBI stand aside and let the Park Police do the investigation into the death of his BEST FRIEND and POWERFUL MEMBER OF WHITE HOUSE STAFF, ole boy Vince.
Hmmmmmmmm........
