This proposed legislation would be great for future genealogists if they can gain access to the database (which I doubt). However, there are huge security and privacy issues involved.
Arizona Bill 1475 was introduced by Republican State Senator David Livingston and would require teachers, police officers, child day care workers, and many others to submit their DNA samples along with fingerprints to be stored in a database maintained by the Department of Public Safety.
“While the database would be prohibited from storing criminal or medical records alongside the DNA samples, it would require the samples be accompanied by the person’s name, Social Security number, date of birth and last known address,” reports Gizmodo. “The living will be required to pay [a $250 processing fee] for this invasion of their privacy, but any dead body that comes through a county medical examiner’s office would also be fair game to be entered into the database.”
