As I would say if I got 5 min to testify before a congressional committee:

"Gentlemen, it has been suggested that, since Google and others have built technology to detect and block pornographically explicit pictures and videos, that they could build technology to block copyrighted pictures. This is simply not true. Please bear with me and I can demonstrate this. [show two pictures] Can you tell which of these is pornography? It's like Justice Stewart said: 'I know it when I see it'. [show two identical pictures] Can you tell which of these is a copyright violation. [pause] You don't have to peer TOO closely, they are absolutely identical. But the author signed contract allowing me to duplicate and display copies of the one on the left, and did NOT allow me to duplicate and display copies of the one on the right. Determining whether something is a violation of copyright requires one to know details how a court would evaluate fair use exceptions, as well as knowing the details of contracts between two third-parties you may not even know. This is not difficult, it is impossible."
