I never said he is guilty in terms of being found officially guilty. But I do think it's reasonable to question his claim. If he was doing "research", why was he doing it alone? If he was really interested in "research" in terms of how much damaging content was on the Internet, why not approach the authorities and volunteer to assist them in investigating what was out there?
Sorry, but I just find it a bit difficult to believe. Maybe he was only doing research, but I have my doubts...
