What Mr. Heaps has just said is certainly true. These days media is such that any allegation immediately blows up and travels the Internet. I guess the difference I see is that the counsellor process is a little different from a legally framed process that demands a ministerial investigation and then includes a suite of sanctions and legal appeals, rather than a common-sense ability to look into the facts and deal with whatever the allegations are in a practical way.
Presumably if an allegation were raised that the counsellor thought was valid, in making whatever investigations he makes, that would assist in the host country, or whatever. Sometimes there are other international judicial forums where these things can be dealt with.
