That is awful what is happening to your brother. I had no idea that this was occuring anywhere, but a quick look on the web it looks like it is occuring in China, Australia, New Zealand, England and Canada as well. It seems the idea is to replace fingerprinting with DNA sampling. It seems to go along the lines of guilty until proven innocent and until then and even after you have no rights.

Page 22 (Newslines The military) – Military DNA samples may be used in crime probes – The 2003 Defense Authorization Act allows local and state law enforcement authorities to request a federal judge for access to the military DNA database.  The database was created for the purpose of solely identifying deceased service members.  The bill, from draft to passage, quickly moved without debate and/or public examination.  Objections are being raised over the loss of privacy.

Over $8 million is budgeted for crime labs in Baltimore, Berlin and Hagerstown. Along with other tests, these labs will perform over 10,000 blood and narcotics chemical analyses and 1,000 firearm analyses during the year. Also, a new 2002 law will expand the range of offenses which require convict DNA samples

DNA is an extremely powerful law enforcement tool. It has convicted many persons accused of crimes. DNA may also be the most valuable tool we have for proving innocence as well and it has even caused the nation to rethink the death penalty. Obtaining a nationwide database of DNA "fingerprints" could revolutionize law enforcement identification. Every State now requires DNA samples from some convicted felons and at least 5 states compel DNA samples from all felons. Law enforcement authorities have embarked on federal and state programs to compel DNA samples from all arrestees as well.  The Combined DNA Index System (CODIS) is already underway and is designed to be a fully integrated local, state, and national law enforcement system of DNA records. And some are arguing for a national database that would even obtain and record the DNA of all newborns, immigrants and visitors to the United States.
