Juvenile court records are sealed once the juvenile comes of age on the assumption that a young punk has a better chance of becoming a non-punk if the record of his punkdom doesn’t follow him forever. It’s a good law, and in light of Miss New Jersey’s plight, I’d like to propose a 2007 update: Seal Facebook.

Seal MySpace too, while we’re at it. Let’s come up with some way to erase all record of a person’s stunningly stupid Web page the minute he or she turns 21 and realizes it is actually not the world’s coolest thing to pose for pictures while, for instance, biting someone’s breast (particularly while that someone looks vaguely annoyed).

This law would certainly help any future Miss New Jerseys. As you’re probably aware, the current one, Amy Polumbo, has been the victim of a blackmailer who threatened to expose compromising pictures of her he’d grabbed off her private Facebook account.

Like most summer stories involving young women, beauty pageants, and possibly softcore porn, this story did not go quietly to page 38. Earlier in the week, Miss New Jersey appeared on “Today,” insisting the pictures, which she refused to show, weren’t really bad. Yesterday, she was back again with Matt. This time, she showed the pix.

Really bad.

The most provocative one did indeed show her boyfriend biting her fully clothed breast. (NBC exercised its journalistic responsibility by keeping this image on air an inordinately long amount of time.) Another shot showed Miss N.J. with her legs — again, fully clothed — in a position that could only be called … non-vertical. Unseemly as these photos were, we as a country are now faced with two choices:

We can express our shock and declare Miss New Jersey a shameless hussy unfit for even a Burger King crown. Or we can assume that pretty much everyone does something icky, if not downright illicit, in college, and from now on, thanks to the Internet, we are going to see all sorts of pictures of them doing it. That being the case, we’ll either have to write off pretty much everyone with a Facebook page as an utter degenerate, or we’ve got to stop being so shocked.

Right now, I’m trying to do the latter.

The reason is not just that Miss New Jersey seems no worse than other young women her age. It’s also that I just had dinner with a friend and her delightful daughter, who is heading to college this fall. When talk turned to the pictures on her Facebook page, however, her mother said, “Yeah, with her tongue out in all of them.”

Really?

“Not all of them,” the daughter said.

“Is your tongue, like, licking people?” I asked of the young woman I’d admired ever since she cut her hair off right before her bat mitzvah and donated it to charity.

This otherwise perfect daughter blushed.

So here’s the deal: If there are pictures of this lovely lass licking her friends on her Web page, and pictures of the young woman accomplished enough to become Miss New Jersey with her legs in the air, we just have to accept that everyone’s Facebook is a fount of foulness, a citadel of shame that should be sealed upon graduation.

If that’s technologically impossible (is it, Mr. Jobs?), let us at least agree not to judge folks by their Facebook follies. Otherwise, there will be no one left to hire, date, marry, elect to public office, or crown Miss America.

There will, however, be plenty to party with.
