No, everybody's DNA is not in the DNA database. CODIS (which is the U.S.A.'s DNA database) only contains DNA samples from individuals who have been convicted of certain crimes, individuals who have been arrested on felony charges, missing persons, and unidentified bodies. Different states have different rules for deciding who's DNA goes into the database. All fifty states take DNA samples from people convicted of major felonies, such as sexual assault and homicide. Forty-seven of the fifty states take DNA samples from everyone who has been convicted of a felony. Some states, such as California, take DNA from everyone who is arrested. Some states take DNA from everyone who has been convicted of a crime, even a misdemeanor crime.
