Gunning for p2p?

In a Washington Post Op-Ed, Lawrence Lessig notes the parallels between the rationale for regulating P2P through liability for tool vendors and the rationale for regulating firearms by creating liability for gun manufacturers: Bytes and Bullets

But there is a silver lining here, and it has to do with, of all things, a very old technology: guns. For if Congress passes this bill, on what principled basis can it then refuse to hold gun manufacturers responsible for the crimes committed with their technologies?
