The one I've listened to for the longest time is G. Gordon Liddy. Check out his credentials.....
G. Gordon Liddy has done it and speaks from personal experience. Who else has been a prosecutor, a defense lawyer, admitted to the bar of the Supreme Court of the United States, an Army artillery officer, and the youngest Bureau Supervisor in the FBI who out drew and captured a man twice on the Ten Most Wanted list?
The G-Man has also been a high Treasury official, a White House aide and a maximum security prisoner. He wrote the memo that led to the creation of the DEA, helped start the first Sky Marshal program and selected their weapons, and is the author of three best-sellers.
Liddy is a Israeli trained paratrooper who has jumped with the elite Israeli army, Liddy has the NEED FOR SPEED. He drives a 200mph sports car and rides two Harley Davidsons, has piloted a Soviet aerobatic plane and World War II allied and Luftwaffe aircraft.
