And here, (at CJLF's Crime and Consequences) we find the following excerpt, describing an examplary incident that demonstrates precisely why the registration laws are nothing more than a feel good, politically correct, ineffective, (and unconstitutional if not un-American) pieces of paper containing worthless ink.
Convicted Sex Offender Strikes Again, Victim Only 16: Angel A. Perez Jr., a 32-year-old convicted sex offender, failed to register his new address with police. He also had several outstanding warrants for larceny, which would have qualified him for diversion programs for "nonviolent" offenders. Now, he's charged with raping a 16-year-old girl in a park near her home, an ordeal that lasted for around an hour, according to Brian Fraga's story for the Standard-Times. Repeat offenders are just that, and the only way to protect society from them is for them to be incarcerated for increasingly longer periods of time.
