Should Police Be Allowed to Collect and Retain DNA Samples from Arrestees Before Conviction?
Debate whether routine DNA swabbing upon arrest solves unsolved violent crimes or builds an unconstitutional biometric surveillance database of innocent citizens.
Pick a Side
Choose a position to defend, or let fate assign your stance.
Arguments FOR
1. Solves thousands of cold-case rapes and murders by uploading arrestee profiles to CODIS
Mandatory booking DNA swabs immediately match unsolved crime scenes, taking serial rapists and murderers off streets before they strike again.
2. The US Supreme Court definitively upheld the practice 5-4 in Maryland v. King (2013)
Justice Anthony Kennedy ruled taking a cheek swab upon arrest is a legitimate, routine administrative booking procedure analogous to fingerprinting.
3. Instantly exonerates wrongfully arrested innocent people before trial
Comparing an arrestee's DNA immediately against crime scene samples can establish total innocence within hours, preventing wrongful pre-trial detention.
4. Creates powerful deterrence against future criminal recidivism
Arrestees who know their genetic profile is permanently logged in the national CODIS database are significantly less likely to commit future violent crimes.
Arguments AGAINST
1. Directly violates the Fourth Amendment guarantee against warrantless, suspicionless searches
Taking an individual's personal genetic code before they are convicted of any crime treats an innocent, unconvicted citizen as guilty.
2. Justice Antonin Scalia famously declared: 'Your DNA can be taken and entered into a national database if you are ever arrested... This will solve many crimes. And so would the taking of your DNA with or without arrest...'
Scalia warned in his dissent that treating DNA like fingerprints opens the door to mandatory nationwide genetic databanks for all citizens.
3. Arrests are frequently baseless, arbitrary, or dropped, yet DNA profiles remain permanently stored
Police routinely arrest citizens during protests or false identifications; even after charges are completely dropped, the state keeps their DNA forever.
4. Contains infinitely more sensitive private information than a physical ink fingerprint
A DNA sample reveals an individual's medical predispositions, family tree, hereditary diseases, and biological traits, exposing immense private data.
Counter Questions
Questions to challenge claims and probe deeper into trade-offs.
- Why did Justice Antonin Scalia write a scathing dissent in Maryland v. King (2013) calling the ruling an assault on the Fourth Amendment?
- If a citizen is arrested for an administrative protest and charges are immediately dropped, how difficult is the legal process to expunge their DNA from CODIS?
- Why did the UK European Court of Human Rights rule in S. and Marper v. UK (2008) that retaining DNA of unconvicted individuals is illegal?
- How is genetic DNA fundamentally different from a physical ink fingerprint in terms of private medical information?
- Should DNA samples be automatically and permanently destroyed the moment an arrestee is acquitted or charges are dismissed?
