It is great to see others posting on Christmas! This issues discussed here are Paramount! A database is a powerful tool and in the wrong hands are extremely dangerous.
Besides issues with deviants, biometric info/data are being compiled on most everyone in the U.S. and abroad. This behavior exhibits itself in both public and private arenas. It is safe to say the uses boggle the mind.
Some uses of the database are unconstitutional. SORNA (The regime) uses a particular database and it falls in that category firmly.
