Perl script used to sniff out sex offenders leads to arrest

By using 1000 lines worth of code over several Perl scripts, former hacker and currrent Wired editor Kevin Poulsen was able to identify 744 sex offenders with MySpace profiles. 497 MySpace users are registered for sex crimes against children, with six of them listed as repeat offenders. At least 243 of the 497 have convictions in 2000 or later. Poulsen reveals in a Wired article how he helped to indentify and catch a known sex offender who was preying upon young boys through MySpace.

"In May, I began an automated search of MySpace's membership rolls for 385,932 registered sex offenders in 46 states, mined from the Department of Justice's National Sex Offender Registry website -- a gateway to the state-run Megan's Law websites around the country," Poulsen wrote. "I searched on first and last names, limiting results to a five mile radius of the offender's registered ZIP code."

The code that Kevin Poulsen quickly wrote was far from perfect and turned up many false or unverifiable matches. Poulsen then worked part-time to sift through the data and manually compare photographs, ages and other data.

"For every profile with warning signs, I found eight without," he continued. "In many cases, the sex offender's MySpace profile is a window into a seemingly normal life: Their comment board is innocent; their image gallery contains a wedding photo or two; the underage friends on their list, if they have any, turn out to be relatives, or adults lying about their age to game MySpace's old security model -- in which only 14- and 15 year-olds enjoyed private profiles."

The result of all that work culminated on October 2, 2006 when New York's Suffolk County Police Department apprehended 39-year-old Andrew Lubrano, who now faces his his fourth arrest for a sex crime over the last 20 years.

Today, Kevin Poulsen is releasing to the public the code he wrote that helped to identify sex offenders on MySpace. The download link may be found here, along with a few pages of explanation on exactly how the code works.

Uh.... right. Put them in jail forever for consensual sexual acts (which most cases of 'child sexual abuse' are). That is not fair at all.

Sexual offender is a loaded term that makes it seem like you are a frothing at the mouth, Jack the Ripper wannabe, who would force someone into a sexual act.

On the contrary. Most 'child sexual offenders' are people who are arrested for consensual sexual acts with children or teenagers that the parents find out about, and are upset over, not because they are protecting their children, but because they are worried that their children will get pregnant and it will impact on THEIR life.
There are the few like the Megan Kanka killer, but they are very rare and are usually driven to their acts by sexual frustration and need.
Something that the laws THEMSELVES create, and make it MORE dangerous for children.

Most adult sexual offenders are arrested for raping a woman, when there is little evidence to show that rape actually took place other than fluids in the woman in question.
Women, girls, men and boys do lie about being raped, yet we do not make a lie-detector test for any victim of sexual assault a required thing.
I've had 2 of my closest friends arrested for rape, and both of them aquitted because the woman's prior boyfriends have come out and said that they tried the "Cry Rape!" ploy with them, and it didn't work.
