Whether or not you agree with the anti-smoking movement, you can concede that it worked. Why not apply the same template to those who would invade another’s space? We don’t want to outlaw cameras or otherwise limit free expression, but we can certainly make it unattractive and unacceptable to intrude on others. Next time someone takes your picture or posts it on the Internet without your permission, raise the roof. Point a finger. Stand athwart civilization and yell, “No more.”

When others are victimized by another’s lack of scruples, be outraged. And never publish or distribute images of anyone without his or her permission.

It’s the least we can do — and not do — for Tyler Clementi.
