I do own shares now. And will buy more if it drops at all.
Your right, an attorney would not take this case pro bono. They would take it for a percentage of the damages awarded to the class. If the company is profitable and/or generating revenue, an attorney would take it in a second if their was fraud on the part of the directors.
You might be confused about directors insurance. This insurance is typically provided by the firm to a director to indemnify their actions while sitting on the board in violation of the duty of care and or to pay for defense fees. Directors insurance cannot by law indemnify a director who has violated the duty of loyalty in committing fraud. Tanking a stock price for your own financial benefit is not protected behavior under directors insurance. (though it may cover the legal fees prior to a guilty verdict)
