JFC, have you never been to a hacker con? Drinking and drug use is not exactly rare.
No, I have never been to one before. I was just asking a question, sorry if it was a stupid one.
Drug and alcohol use, even to "dangerous" levels, is probably 20-30% of the high-profile people in the hacker scene (or, really, people in the tech scene in SFBA in general), at the very least. If Barnaby were a known teetotaler, one of the hundreds of people who knew him pretty well would have stepped forward. Given that they haven't, you can assess with high confidence that this is what it looks like, rather than a grand conspiracy.
