Agreed it's a theory, though someone mentions some other site with more on the story in the comments.. However, not to excuse falsifying evidence, the 30s buffer example you mention wouldn't cover the case where you found the stash more than 30s earlier and have already disturbed with the otherwise valid crime scene.. I'd imagine in some sort of hot pursuit situation it would be pretty easy to do this and forget the button, especially if you've been working for years without them..
