Based on the link you provided, it clearly does.
1994 was the beginning of the sex offender registration program for most of the country (
Jacob Wetterling Act) followed by
Megan's Law in 1996.
According to your link, the forcible rape rate between 1986 (earliest the table goes) and 1994 (beginning of national sex offender registry) hovered between about 38-42. After 1994, it takes a sharp decline, going down each and every year from 39.3 down to 31.8 in 2001. Between 2001 and 2005 (latest the table goes), it hovered between about 31-33.
What about that table was supposed to suggest the sex offender list doesn't work?
True, there may be other reasons for the decline in forcible rape, but it certainly doesn't prove "it doesn't fucking work".
