Sorry, which 'East Germans' are you referring to? All East Germans? If so, why? Is there evidence that EVERY East German athlete was on drugs? If so, can you provide a reference to that?
As far as I recall, there are some Stasi documents that illustrate SOME East Germans were on doping programmes. Is that evidence comprehensive proof that EVERY East German was? No, it isn't. Can we infer that ALL East Germans were, because of the evidence that shows others were? We could, but in that case should we then infer that every athlete that trained under Koch's coach, Wolfgang Meier, was on drugs - Marie Jose Perec? Should we infer that everyone that traineder under Ekkart Arbeit was on drugs - Denise Lewis? Should we infer that every team mate of Marion Jones who was trained under Trevor Graham was on drugs - Shawn Crawford, Chandra Sturrup, Me'Lissa Barber? Should we infer that every athlete who once trained under Chuck Debus was on drugs - Merlene Ottey? Should we infer JJK was on drugs because of the allegation against Florence and Bobby Kersee by Darrell Robinson?
Or are we going to cherry pick who we think was clean because we like them and they are our heroes? The Women's WR for the 100, 200, 400, 800, 100mh, HJ, LJ, SP, DT and heptathlon were all set in the 1980s. But let me guess, you'd happily see all the Eastern Bloc records go and keep the US ones? You think maybe 10.49/21.34/7291 are ok? Dude, wake up and smell the coffee.
You cannot ban 'every' East German because, guess what, there isn't evidence that every one of them was on drugs. Does common sense tell us they all were? Possibly, but then common sense tells us some of the performances from Western athletes in the 60's, 70's and 80's was assisted, but we don't have all the evidence for that either.
