At what point does the deducing it yourself become allowable(if ever)? If I work at Amazon, and see Bezos in a conference room banging his hands on a desk and raging(which is not his normal behavior at all), I sell AMZN based on that, and then it turns out they had a massive data breach that tanks the stock price, is that insider trading?
