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.
