Kopple always appeared to me to be a serious newsman. Yeah,he had to do some tapdancing as speaking head for ABC,but he still seemed to find a way to get the truth through,even if it was subdued.
Let's not forget to honor Sam Donaldson while we are at it. He basically was forced into retirement for demanding Bubba Bill answer his questions about Monica.
Telling the truth seems simple to most of us,but it gets a LOT more complicated when you are risking multi-million dollar contracts and the loss of a 40 year career because you KNOW that no other news organization is going to hire you.
