Here's another remarkable moment in 2012. Everybody knows that Wal-Mart ( WMT 0.83% ) shareholders have little voice. After all, the founding Walton family owns about half the company's stock, so right out of the gate we know that independent shareholders don't have a chance of culling a majority vote. However, given that backdrop, a surprising number of shareholders voiced their displeasure with some factors at Wal-Mart, including the international bribery probes coming to light in the last 12 months.
