After a crimminal serves his/her debt to society, then all rights and privileges should be restored.
The 9th amendment states:
"The enumertaion in the Constitution of certain rights, shall not be constrtued to deny or disparage others retained by the people."
Every citizen has the "others (rights) retained by the people" which includes the right to privacy.
There is no argument if her mother had known there were child molesters living in a halfway house across the street from her, her daughter would still be alive today.
Since we cannot keep rapists and pedophiles in prison forever as we should, we have the basic, fundamental right to know who and where they are. Period.
The very idea of the privacy of a child molester being more important than the safety of our children is absolute 100% Grade-A US Prime American stupidity.
