Basically, they say Ahmed did more than just what is reported in the article, and they can't publicly say what he did - because that's private info about Ahmed that they're legally obliged to protect.
Now I'm not taking a position in favor of the college or in favor of Ahmed. I'm just saying, it's not all black (or white). The National Post article is biased and we're missing some info. We should remember about that before going crazy on the witch hunt.
