I see what you're saying, but wouldn't it make sense to blame someone who cast his vote in favor of a corrupt action?
The thing is, shareholders don't even get the opportunity to cast their vote in favor of a corrupt action. The things they get to vote on at the annual meetings (at which most shareholders vote by proxy--it's like an absentee ballot) are incredibly boring. It's stuff like "should we extend the term of members of the board of directors from three years to four," "should we expand the board from 6 people to 8 people including two more outside directors," blah blah, incredibly boring stuff.
Actual corporate policy, like "should we stop making this dangerous product," "should we fire the CEO," "should we stop using this toxic chemical," "should we cook the books" (haha), or "should we close our Indiana plant and outsource to China" are never voted on in shareholder meetings. Those decisions are not up to the shareholders. They're up to management or, in certain cases (e.g. should we fire the CEO), the board of directors. I can't think of anything that could conceivably be considered a "corrupt corporate action" that the shareholders would even be asked for their input on, let alone that the shareholders would get to cast deciding votes on.
In light of that, does it make sense to walk into a corporate office, notice an ill-voting shareholder, and lend him a sneer? I know he didn't have a huge impact on the vote, but he voted regardless
Apart from the huge problem I just mentioned above--so, even assuming that for once the shareholders somehow got to vote on something meaningful/corrupt--there are two problems with that scenario:
- First off, if person A walks into the headquarters of corporation C and sees shareholder B there, how does A know that B is a shareholder? Not to mention, what the heck is B even doing there--the only shareholders you're likely to see at a corporate office are employees who happen to be shareholders because they have stock options.
- And second, even if there's a plausible reason for B to be there AND A somehow knows B is a shareholder, how does A know which way B voted, or even whether B voted at all? If you've got a big corporation, you may be talking tens of thousands of shareholders, all of whom get proxy-voting materials in the mail, many of whom just throw the stuff away and don't even bother voting (why bother, when all you're asked to vote on is incredibly boring stuff). And for those who do bother to vote, it's a secret ballot, like pretty much every other ballot in this country. There's no way for A to know how B voted, unless B tells him.
So... all this is a long way of saying "no."
Sorry! But at least, by ditching that idea, you're avoiding a major factual mistake. Like I said earlier, there are ways you could do this: either (1) a small corporation in which the shareholder has actual influence, whether because he's also a board member or officer, or because he's a major investor who can actually call up management on the phone and be listened to; or (2) the person who gets mad at the shareholder is a nutcase or a grieving mom or [insert other hugely emotional type of person here]. Those are the only ways I can think of that this scenario could be plausible.
