Google provides diffs of their privacy policies, so I imagine it would be possible to tell whether any given practice was in violation of their stated policy at the time of the infraction by looking at the policy's history. Also, I don't think it matters whether someone has read the privacy policy when they try to take you to court. Oh, you didn't read that I plan to share your information? Guess whose problem that is.
