Exactly! If we had a DNA database we could quickly clear people as innocent.

Instead we rely in inaccurate authentication measures like birthdays and names and photos...hence endless suffering.

DNA would positively or negatively identify people.

Besides, people are already voluntarily doing this at airports as part of the CLEAR program. So your horrible awful terrible nightmare scenario...literally goes on every day at major American airports.

Only when you have a sample to compare it to that definitively came from the perpetrator (not just “was found at the scene and can indicate that whoever it came from was present”.)

That's actually not all that common.

Is the TSA the FBI? They're not looking for perpetrators, they're looking for terrorists. I promise you the US government has a vast database of biometric information of suspected terrorists.

The fact we all have to suffer thru terrible, imperfect authentication techniques like looking at your birthday shows we should have a database to save us all the grief.

Honestly all your arguments are actually GREAT reasons to have a national DNA index.
