A: there are multiple criteria for placement in CODIS. All felons are added, as are many citizens who fall into 6 other categories. 

Firstly, if you think you are not at risk, then know this: in Britain, approximately 8% of the population is in their equivalent database, and 20% of those in the database have no criminal record (Moore). The numbers are higher in America. 
Here are the six main categories of non-felons in the database: 
​
1. A disproportionate number of Black Americans:
  • About a third of the African American population is surveilled through DNA databases, while roughly 7.5% of the Caucasian population is surveilled in this manner (Cox)
    • 42% of black males are in the database (Moore)
    • Mr. Hank Greely, a Stanford University Law School professor, stated that 40% of the database is comprised of African Americans, whereas African Americans only make up 12% of the national population (Moore)
2. Infants:
  • All 50 states and Washington D.C. require a blood spot test on every infant which is then accessible by all state and federal governmental agencies (Newsweek).
3. Minors upon arrest:
  • 35 states require that any minor arrested or detained, regardless of the crime, must be swabbed and added to CODIS (Moore).
4. Misdemeanors: 
  • 16 states take DNA samples from those convicted of misdemeanors and store the DNA indefinitely (Moore).
​5. Veterans: 
  • The VA implemented a policy of DNA collection for veterans (Reiss).
    • "Watchdog groups worry about genetic discrimination by insurance companies and employers” for veterans benefits if they find genetic markers indicating predisposition to health conditions -- but this information can be accessed by the FBI and in general serves as surveillance over veterans. 
6. 23andme users:
  • Anyone who participates in 23andme genetic sequencing is susceptible, as “23andMe has...suggested that its longer-range goal is to collect a massive biobank of genetic information that can be used and sold for medical research and could also lead to patentable discoveries” (Weiss). Their privacy agreement with users is open ended and has been used to assist in criminal cases as well as in conjunction with the NIH (Newsweek).
  • Furthermore, those who submit DNA information to Ancestry.com or other similar sites are at risk, as that information is accessible by the US government without warrant.
