i'm pretty sure that the indian atheletes have been framed: as non carborundum said in a comment.
On the recent "doping scandal" that has hit Indian athletics. It's common knowledge that all athletic events' winners use banned substances, mainly anabolic steroids. It's just that the masking techniques used in the US, China and Europe are more advanced, so they do not get caught that easily. When our own athletes are caught, there is always this sanctimonious humbugging that's thrown left, right and centre by couch potatoes who wouldn't dream of putting their bodies on the line for the country. This sort of criticism is no less than treachery in my view. Unfortunately, no one really cares.
