Corporations and Free Speech

So the Supreme Court ruled moments ago that corporations have the same free speech rights as individuals. Do other basic rights apply to corporations, as well? For instance, will corporate officers be able to take the Fifth if they feel their testimony might incriminate the companies they represent? And what about Second Amendment rights? How much more exciting and interesting will the Microsoft vs. Google and the Google vs. Apple wars become if those companies can now keep and bear arms?


UPDATE: A friend responds to this by observing that, "Conservatives will be happy with the 2nd amendment rights just as long as Microsoft and Apple can't get gay-married."
