A National DNA Registry IS sound public Policy
Background
The United States currently maintains a DNA database, called the Combined DNA Index System (CODIS) which host the National DNA Index System (NDIS). NDIS includes DNA profiles from federal, state, and local investigations.[1] DNA submitted to NDIS must fulfill strict regulatory requirements. For instance, the government is only authorized to collect DNA samples from sex offenders or those committed of major crimes.
While the US has restrictive standards for DNA collection, the United Kingdom maintains a significantly broader DNA database, called the National DNA Database (NDNAD). With over 3 million DNA profiles, "5.2% of the UK population is on the Database, compared with… 0.5% in the USA."[2] The UK has found many benefits from this larger database. In this blog post, I will argue that the creation of a database with the mandatory collection of DNA from every American citizen is good public policy.
Argument #1: Better crime fighting
With a national DNA registry, law enforcement's ability to solve crimes would increase significantly. In the US, less than 25% of all violent crimes and only 7% of all property crimes are solved.[3] That is absurdly low. A national DNA registry that includes DNA from all citizens, however, could play a huge role in solving these crimes. DNA is powerful. In 2018, the Golden State Killer was caught after investigators searched a database which contained several of the killer's distant relatives.[4] When DNA has been added to criminal investigations: "More than twice as many suspects were identified… [and] arrested."[5]
Not only would a national DNA registry assist in solving crimes, but it may also reduce the number of crimes that are committed. Studies have found that "DNA profiling makes violent offenders 17% less likely to reoffend, and makes property offenders 6% less likely to reoffend."[6] With a national DNA registry, we could achieve a reduction in first offenses as well.
Argument #2: A national DNA database would reduce discrimination
Another potential benefit of a national DNA database is that it could reduce racial discrimination. It could accomplish this in two primary ways. First, it would create a more racially representative DNA database. While only 13% of Americans are black, up to 49% of CODIS DNA profiles are from black people.[7] As a result, the DNA system we currently use is more likely to contain the DNA of a black person than of a white person, and thus more likely to lead to additional arrests of black people. With a national DNA registry, DNA analysis would not be disproportionately likely to implicate racial minorities.
Second, a national DNA registry would provide evidence necessary for the exoneration of many wrongfully imprisoned individuals. Unfortunately, there is evidence that black people are wrongfully convicted at disproportionate rates, as 50% of exonerees are black.[8] Thus, by providing a more representative database and by facilitating the exoneration of many individuals, a national DNA registry would reduce the discrimination that continues to plague our criminal justice system.
Argument #3: Non-crime benefits
While a national DNA registry would be useful in solving crimes, it is important to consider the other potential benefits. For instance, a massive database of DNA could aid further research in genetics. It could also be used to "define paternity… and identify victims of crime, disasters, and war."[9]
Rebuttal: But a national DNA registry is a huge invasion of privacy
This is a totally reasonable concern. However, I think the benefits of a national DNA registry supersede the privacy risks. If giving up my genetic profile means that I get to live in a society that is safer, more equitable, and more likely to catch criminals, then I would be willing to make that trade. At the same time, I think there are reasonable steps we could take that would decrease the privacy risk associated with a national DNA registry. For instance, we could require that, except in extreme cases, the DNA database could only be used to confirm, rather than to find, a suspect.
Conclusion
There are many benefits to a national DNA registry. With the creation of a DNA profile of every American citizen, law enforcement would be better equipped to fight crimes, criminal activity would decrease, discrimination in arrests would decrease, and many wrongfully convicted individuals would be exonerated. Obviously, such a database has inherent privacy concerns. While it is reasonable to be concerned about the collection of one's DNA, the resulting benefits are well worth the costs. The creation of a national DNA registry is good public policy.

Introduction
A national DNA database would collect data from millions of citizens across the country and store each individual’s genetic sequencing in an online registry for various purposes. There have been debates about whether or not a DNA registry with access to every citizens’ DNA should be implemented. Many nations across the world already store some form of DNA, such as fingerprints, iris scans, etc. For example, the United Kingdom has one of the largest DNA databases in the world and collects data from anyone who has been convicted. The collected DNA information is also stored in the system permanently. However, if one has only been arrested and not convicted, their information remains in the database for a minimum of 6 years, which is renewable on subsequent arrests [1]. As this technology grows, the government wants to expand the reach of the DNA registry and the information it holds. “In the last ten years alone we have gone from collecting DNA only from convicted sex offenders to now including people who have been arrested but never convicted of a crime.” [2]. The creation of a national DNA database consisting of DNA from every citizen collected through a mandatory collection program is not good public policy because it contains sensitive information, infringes on our 4th amendment rights, and can lead to false incarcerations of suspects.
Data Collection Risks
DNA that has been collected for a database doesn’t expire, meaning it can be stored for an infinite amount of time (if it is not manually deleted). They contain sensitive information such as family relations, susceptibility to disease (including hereditary), and even behavioral tendencies [3]. This capability for indefinite storage and unlimited sharing creates a huge privacy risk. There is also the issue of people not wanting to participate in this mandatory DNA collection program. What would happen to individuals that don’t want the government to have their DNA? Would they be arrested, restricted, or targeted in any way? People should have the right to choose whether or not they want to distribute their DNA and its confidentiality instead of forcibly giving it to the government for a national database. Some may consider this an infringement of our 4th amendment rights if the police are able to access the database without a search warrant. The national database is also at risk from hackers which have the capability of leaking millions of people’s data online. The company MyHeritage is an example of such hacking where over 92 million accounts were hacked, resulting in emails and passwords being exposed. Despite DNA data not being breached, this type of hacking is definitely cause for concern [4]. A national DNA database would be a huge risk because of the sensitive information that our DNA contains, hacking threats, and the possibility it is unrightfully accessed by law enforcement.
Contamination Concerns
DNA evidence can be contaminated when DNA from another source gets mixed with DNA relevant to the case. During an investigation, the contamination of DNA can occur when it is collected, transported, or stored. DNA analysis can also be inaccurate and unreliable. In 2015, news about a San Francisco Police Department lab had several “irregularities” or missing gaps in the DNA, which were then filled in by an analyst to complete. The lab went ahead with this poor DNA to search the database to identify potential suspects [5]. This procedure was a violation of the rules implemented by California state laws (as only good quality DNA samples can be sent for analysis) and it’s projected that this misconduct affected as many as 1,400 cases [6]. If DNA samples collected from crime scenes are not being properly processed, it leads to the false incarceration of a suspect. This instance is an example of why there needs to be more restrictions put in place to ensure that DNA is properly handled, processed, and investigated before it is cross referenced with other DNA samples. If every single person’s DNA is in a database, then the probability of more incorrect matches and false prosecutions would increase drastically.
Conclusion
I support a database that collects DNA of convicted criminals, members of the military (for identification purposes), missing persons, and other select cases. However, I do not support the move towards collecting every person’s DNA because it is too invasive. Collecting the DNA information of every citizen is a privacy risk where the ends do not justify the means. The possibility of hackers breaching the data of millions and exposing their DNA profiles is too risky. If the data is stored indefinitely then that makes even more profiles subject to harm or breaches. Police departments with access to the registry may try and access it without following proper protocols, either violating 4th amendment rights or state laws in an attempt to match suspects with poor DNA. It is for these reasons that a DNA registry that collects the data of every civilian should not be implemented and is poor public policy.
