Online vigilantism

It seems all those NBC Dateline sting operations against online sexual predators have caused a lot of people to want to "help." The problem, some law-enforcement people point out, is that "sloppy civilian investigations will push predators further underground, and that civilians may be endangering their own safety," the Associated Press reports. Perverted Justice, "an organization that's dedicated to outing online predators [and helps Dateline with its stings], expects to double its volunteer corps, to 100, by year's end," according to the AP. Then there's Corrupted-Justice.com, dedicated to exposing "the dangers of the vigilante actions being perpetrated by the Web site Perverted-Justice.com and its members."
