It's not morally right, but there exists a paper procedure that makes charges of insider trading unenforceable. The exec with the tons of stock options they want to exercise and take profits from simply has to file a stock sale plan document, then instruct their broker to execute the plan. As long as the stock sale is done per a document filed in advance, and not depending on current market conditions, they get away with it.
Laws/regs need to be changed.
