Law enforcement databases utilize a different type of DNA marker (STRs) than those used in genealogy (SNPs), making them non-comparable. Furthermore, criminal databases are not uploaded to genealogical sites like GEDmatch, and law enforcement has been collecting DNA samples from arrested individuals for about 25 years, though its initial implementation was inconsistent.
Impact: High. This distinction highlights the necessity of using genealogical databases and specialized techniques to bridge the gap between criminal investigations and familial DNA matching, as traditional law enforcement databases are insufficient for this purpose.
