“The goal, justice officials said, is to make the practice of DNA sampling as routine as fingerprinting for anyone detained by federal agents, including illegal immigrants. Until now, federal authorities have taken DNA samples only from convicted felons.

…Peter Neufeld, a lawyer who is a co-director of the Innocence Project, which has exonerated dozens of prison inmates using DNA evidence, said the government was overreaching by seeking to apply DNA sampling as universally as fingerprinting.

“Whereas fingerprints merely identify the person who left them,” Mr. Neufeld said, “DNA profiles have the potential to reveal our physical diseases and mental disorders. It becomes intrusive when the government begins to mine our most intimate matters.”

…Immigration lawyers noted that most immigration violations, including those committed when people enter the country illegally, are civil, not criminal, offenses. They warned that the new law would make it difficult for immigrants to remove their DNA profiles from the federal database, even if they were never found to have committed any serious violation or crime.
