Yeah, along the same lines, the actual definition of insider trading is a lot narrower than people think, there's interactions that would be insider trading if it came from the CEO, but is not insider trading if it comes from a guy who overheard the CEO on the phone in a coffee shop or something. Multiply that by thousands of employees with "sensitive" information having unguarded conversations that they're perfectly allowed to have, and there's a lot of information out there.
