I am not truly optimistic that the culprits and their accessories or their abettors would be incarcerated in the near future for this heinous crime. But I am keeping my eyes peeled on the issue. The interview of the self proclaimed perpetrator, on the BBC, was interesting, who in my view, do not sound a bit of a revolutionist.
At this point, all we do can is guess. And we all know that we all are good guessers like everybody else.
