Biometric IDs are scary. El Chapo was extradited and hauled into U.S. court.

Fingerprints? They cut them off.

Iris/retina scans? They stab them out.

Voiceprint? It varies from common cold to throat cancer to polyps in the larynx, or being grabbed in the throat by a mobster.

DNA? There's a lady across the street thinks you're scary and wants you locked up away from her children, while some "expert witness" exempt from subpoena shows up in court and impresses the jury with a talk on DNA "match sites" and 1,000,000:1 odds.
