Re: Well helloooooo.
"The lack of court orders or subpoenas, while giving access to a confidential database."
And what if you happen to be an employee of the FBI nad have an interest in genealogy? That person then has a legal right to use the database. It's not even "tainted" evidence if it's obtained legally, even without a warrant. The only real difference here is that the FBI have their own specific account.
This is a problem for the US legal system and privacy advocates. It's not currently a problem for law enforcement because they are not breaking any rules. It's the rules that are wrong.
