"The committee was unanimous in its desire not to select Dwain...Taking him to the World Indoors deprives young, upwardly mobile, committed athletes of this key development opportunity...On this basis, it is extremely frustrating to leave young athletes at home; eligible for Beijing, in possession of the qualifying standard and committed to ongoing participation in a drug-free sport...In contrast, we have to take an individual whose sudden return, especially when considered against his previous actions and comments, suggests that he may be using the whole process for his own ends" - UK Athletics 2008

I've bolded (sp?) the parts I think are more relevant to the argument against him. I agree.
