Ya missed my point.
being a convict, R.A. Davis' DNA would've been on file.

Prop 69 is aa real "long shot" on crime solving.

Prop 69 is aa real "long shot" on crime solving. Previous criminals: you've got their DNA

Not without Proposition 89 they didn't. One of its functions was to authorize the swabbing of prisoners and including their DNA signatures in a database.

Non-previous criminals (Suspects): get a warrant for DNA.

Proposition 69 doesn't affect suspects, permission or a warrant would still be required. All you're left arguing about is arrestees.
