If someone makes publicly available data about sex offenders more readily accessible, that might help protect children. But it could also make it more difficult for offenders who have finished paying their debt to society to get on with their lives — theoretically increasing the risk that they will reoffend.

If the names and addresses of people who signed a petition in opposition to same-sex marriage are posted online, it may expose the tactics of anti-marriage activists who fooled people into thinking they were signing something else. But it could also expose sincere gay-marriage opponents to ridicule or worse for simply exercising their democratic rights.

It’s a discussion I’ve had with my students on several occasions, and now the dilemma has spread to guns. The Journal News, a Gannett paper that covers the affluent suburbs of Westchester County, N.Y., and beyond, has put together a map showing the names and addresses of people who hold permits for handguns, which it obtained through a Freedom of Information Act request.

“About 44,000 people in Westchester, Rockland and Putnam — one out of every 23 adults — are licensed to own a handgun,” writes Dwight R. Worley of The Journal News.

As with the examples I cited up top, this is public information. The Journal News has every legal right to do this. But it has prompted an outcry from gun owners and others who say the information ought to be private. One critic has responded by posting the names, home addresses and personal information of every Journal News employee he can find, reports Patrick Clark of The New York Observer.

Greg Mitchell has a detailed report at The Nation, and J. David Goodman recaps the story at The New York Times.

Personally, I’m not sure what to make of this. I’ve been trying to think of a journalistic or social good that has been accomplished by publishing this, and I’m having a hard time thinking of one. I guess if I had a neighbor who behaved erratically, I’d want to know if he might have a legally obtained gun. But that seems like a stretch.

Before The Journal News put together its map, the information fell into a gray area — public, yes, but not easily accessible. Is there a reason for some types of information to be public but also hard to get? Is there anything we can or should do about that in the age of the Internet?
