I'm sure it was the 88 Olympics in Korea 6 of the 8 .....100meter finalists were found to be using PED...Ben Johnson...caught all the flack cos he got caught straight away ....the others got caught later when they re tested the samples as technology got better with the testing....think the same happened in 2012 in London....forgot the weight category..but the weight lifting ended up the 7th place competitor ended up with gold....all of them in front of him...and a number behind him all got pinged for doping
