Duck Duck Goose, it looks like pldennison and others have provided many examples, but I can offer a few more cites:

They are sloppily kept and already woefully outdated after just a few years.

*In St. Louis, Missouri, more than 700 registered sex offenders, or approximately 46 percent, do not live at the addresses posted on the sex offender registry, and many sex offenders (approximately 285 sex offenders released from prison as of May
1999) never get put on the list (Dunklin, 1999). *
and
Recently, it was discovered that as many as 25 percent of registry addresses were incorrect, which has resulted in
citizens having their addresses improperly included on the registry (Webster, 1999).

Some states place the responsibility of updating current addresses on the offender.

*To a certain degree, convicted sex offenders are themselves responsible for the accuracy of the Michigan Public Sex Offender Registry posted on the World Wide Web last week.
Offenders have 10 days to notify local police agencies of their current address when they move or when they are paroled or released from the jurisdiction of the Michigan Department of Corrections.*

*Ms. Griffin fell victim to Maryland’s version of Megan’s Law when her sister-in-law, serving time for statutory rape of a 13-year-old boy, gave Ms. Griffin’s address to authorities as her own.
According to the story, the authorities did not verify the address given to them before sending letters to Griffin’s neighbors and various groups in the community. *

…how conscientious the majority are about keeping a current address on file.

“If they do what they’re supposed to do, the accuracy of the list should be maintained,” Michigan State Police spokesman David Verhougstraete said.

*Typically, the address of about 8-10 percent of the state’s 2,366 registered sex offenders is listed as “unknown” – including 12 percent of the 400 in Jefferson County.
Some offenders have been missing for more than a year, and Draud said police haven’t made finding them a priority.
Louisville and Jefferson County police only recently began investigating sex offenders with questionable addresses. *

Cases of harassment, property damage, and even death of innocent (read: non-child-molesting) people due to mistaken identity.

In Lansing, Michigan, a 26-year-old man was branded as a child molester incorrectly. His name was immediately placed on a Family Independence Agency’s “undesirables” list. The court ordered his name removed, but the damage had been done. The man lost jobs, friends, and family respect, and ultimately, his health was affected (Miner, 1998).

…mobbed and beaten by vigilante neighbors who happened to spot House A on the address list, and never thought to verify identity.

*The 27-year-old Vietnamese refugee was attacked by four men who thought he was a sex offender because his address was listed on the state’s Internet registry. But the address was that of a sex-offender who hadn’t lived at the home for months.
Pham, who has the mental capacity of a sixth-grader, was attacked after playing ball with some neighborhood children on Sept. 22.*

Another that occurred in New Jersey involved the mistaken identity of a man who was thought to be a sex offender. His house was broken into, and he was severely beaten, resulting in the need for hospitalization.

House B is burned down in the dead of the night by neighbors who think they’re doing “justice”.

Among the most notorious cases of violence and vigilantism resulting from Megan’s
Law was the burning down of a sex offender’s house in the State of Washington.
Actually, this one WAS a sex offender, so that’s not exactly what I was saying, but…

While the parents are keeping a sharp eye out on the Devil They Know living 2 doors down, the Devil They Don’t Know (who lives three doors down and molests children but hasn’t been caught yet), [molests their child].

*“This is a political feel-good (solution) to a serious problem,” said Deborah Jacobs, executive director of the American Civil Liberties Union of New Jersey. “It creates a false sense of security.”
These registries focus on strangers. But the real danger lies within the family, where most sex crimes take place, Jacobs said. *

*Finally, as the website candidly and correctly notes, the presence or absence of an individual’s name or address on the website is not an absolute indicator of public safety; in fact, many sex offenders, particularly child sex offenders, are not apprehended, and thus may continue to offend without intervention or rehabilitation. These unknown persons may pose a far greater risk to the public and to children than those offenders who have been caught, punished, and, in many cases, rehabilitated. *

Constitutionality or morality aside, the risk of harm that can be done to innocent people, IMO, outweight the questionable benefits of having a list - especially if that list is not kept absolutely up-to-date with verifiable addresses. The stigma attached to sexual predators is massive - I see no justifiable reason to have it ever attached to an innocent person.
