Why is Google Responsible?

Well, Google is responsible to a certain extent. Google's responsibility stems from its corporate values and the fact that even kids use it. But they also have control mechanisms and that is why they take down videos that are reported as offensive (after human screening). It is a self regulating system based on usage. If you see it and find it offensive, report it.

But this high profile case aims to pass a legislation that can so easily be misused. Who will screen? How many people will be needed to police the net? These same questions were raised for the radio and the TV and it resulted in government regulation.

As far as this case goes, there is no absolute answer here - No right or wrong. It was an offensive video, but they removed it when they received the complaint. On the basis of this doubt alone, these guys should be left off the hook. The internet is the last bastion of free speech. It needs to stay that way.
