The States are building “fusion centers”, in some cases outside the state boarder. These databases will be linked to federal databases. It’s not hard to imagine some unspoken “temporary data exchanges” being set up, where data can be exchanged with very limited access (two individuals) and subsequently deleted by either.
There was a story locally about a prison guard accessing medical records of a free civilian. Seems the prison guard had a pitbull, because how could you be cool without one, and this pitbull bit a 12 year old on his street. A lawsuit was a very a distinct possibility. The prison has a single officer with access to local hospital records, so they can confirm the prisoner’s claims about their medical conditions. The guards conspired to access the 12 year olds private records. => The point being, if something can be abused it WILL be abused.
