Re: it all comes down to size
Actually, do discount something when evidence is lacking. Don't discount it all the way down to zero, but "because it is possible" is not enough to believe something. It is possible that I run a group of people who break into peoples' homes, yours earlier today, and insert malware onto any computers found there. We are very good at getting through locks without leaving a trace, and our malware hides in the firmware where you can't easily find it. Prove that didn't happen. That is not a good enough argument. I believe this story to be unlikely. The things stated are feasible, but with the lack of substantiation from external sources or release of evidence, I believe it to be less likely.
