From the beginning I had some doubts. The results came too quick and were too wild. Yes, they are probable and can be correct. But before you charge somebody for murder of 150 souls, you should have more solid evidences. Not so many speculations and list of unanswered questions.
From my point of view, people like Simon are reasonable opposition, forcing investigators not to draw unfounded conclusions. Media are hungry for "strong" scenarios and Simon is a kind of counterbalance. Regardless he is true or wrong now.
