What puzzles me is the ‘double standards’. In the 100 (SF - I think) Asafa was totally out of his lane (not only ON the line - as the Canadian runner) … and the comment was: He did not ‘obstruct’ the athlete in the other lane. The same scenario in the relays - but yet a DQ? I am not Canadian - is sad about the highlight of a ‘medal’ and afterwards the tears of ‘no medal’.
