I believe the adoption laws regarding sealing need to be BACK-dated. At one time, these records were never sealed from the adopted person. It was only around the WWII era that they started sealing them from adopted person.
Beginning in the 1930's, states began sealing them from the general public, then from the first parents, then from the adoptive parents, and finally from the adopted persons themselves. This went on in all but 2 states. Kansas and Alaska never sealed records from adopted citizens.
Now, 4 states have gone back to giving ALL adopted citizens equal access rights, on par with the rights that non-adopted citizens have.
It's always important to note that these records do not seal when a child is given up for adoption. It is only if an adoption finalizes that the records seal. This means that if I was given up for adoption, but never adopted (or my adoption failed,) then I would always have access to my record. In fact, not only would I have access to it, it would still be my only legal record of birth! Being given up for adoption did not take away my right to access my own birth record. Being adopted did.
Sealing these records never had anything to do with "protecting" the first parents' identities. Indeed, in many states, first parents were some of the first people (besides the general public) to be denied access, while adoptive parents and adopted citizens still had access.
Private criminal lawyers do not get paid a salary. They get paid by clients. Prosecutors and public defenders get paid a salary but they usually work for a county, not for a state. In general, more populated counties pay better than rural counties and western states pay better than eastern states. The federal public defenders and u.s. attorneys get paid by the United States and that pay is the same in every state. In my Western state, the large urban counties pay about three times as much as the rural counties for prosecutors and public defenders.
