The problem I have with the shoplifting analogy as presented is that someone unfamiliar with SOPA might conclude that the website at risk must also be the victim of the crime. How about analogies to other crimes like stealing from another customer, assaulting another customer, etc. What's ironic is that the bar/nightclub industry is effectively governed by such a law. It seems that, when patrons decide to do bad things in a bar, the government can revoke the establishment's liquor license. Even the number of police visits to an establishment due to customers' bad behavior has been used against the establishment. While I might have sympathy for the government if the bartenders were encouraging drunkenness, few other establishments must worry about their own culpability when a customer does something bad on premises.
