An End Run on (US) Copyright Law

Google's Managing Counsel (Litigation) Michael Kwun has a letter to the editor of the Washington Post in reply to an opinion piece by a Viacom lawyer. In this letter Mr. Kwun states that the law is clear and on the side of Google. It also suggests that Viacom themselves seem unable to accurately determine what videos infringe on their content, so their expectation that Google can do it (and do it at Googles cost) is unreasonable.

The letters suggest Viacom submitted a large number of false take-down notices. I wonder if there can be a class-action lawsuit against Viacom on behalf of those whose files were improperly revoked. Viacom seems to have no problem infringing the rights of other people who they incorrectly claim were infringing their rights.
