100 of Something

In 1972, Richard Nixon brought us a scandal of the highest order. In 1976, Alan J. Pakula brought us Robert Redford and Dustin Hoffman in "All The President's Men." A thriller in which no one is shot, stabbed or poisoned. Or blown up. Or thrown out of a building. Wait a minute... What the hell kind of thriller is this? A guy gives vital information to a protagonist and is alive two scene's later to talk to the protagonist *again*?? Oh how little they knew in the old days... Or, maybe they just knew how to do it right. Do it without crutches like speeding trucks, buses or sniper rifles.
