FBI Expands DNA Collection

DNABeginning in April, the FBI will greatly increase its collection of DNA samples. Until last month, the FBI only collected DNA samples from people who had been convicted of a crime. They use those samples to test against DNA found at other crime scenes. The database helps the Bureau solve new crimes.

The new policy allows the FBI to store the DNA of suspects who have been arrested but are still awaiting trial. It also allows the Bureau to store the DNA of immigrants who have been detained.

The FBI runs DNA found at crime scenes through the database every week. If they get a match, they know that that person was at the crime scene. According to the FBI, thousands of criminals have been convicted using DNA evidence, and over 200 people who were wrongfully convicted have been cleared.

But opponents of the new policy say that it violates privacy, guaranteed under the Fourth Amendment to the Constitution. U.S. law holds that a person is innocent until proven guilty. Opponents to the FBI’s policy believe that a person who has not yet been convicted should not be forced to submit his or her DNA to a criminal database. They feel that DNA should not be collected from a person accused of committing a crime unless it will help solve that particular crime.

Supporters of the new policy say that the potential privacy violations are worth it because DNA is so accurate and effective in solving crimes.

    Forensic scientists do NOT test the DNA of platns! That’s just something that CSI made up. You could determine that it was the same species of plant (by morphology, etc.) but that is as far as you would go with that.I would say toxicology most. There is an entire area of forensic environmental toxicology in which people study the toxins that are put into the environment in industry. Soil comparisons too. This is a huge part of trace chemistry.I’m sure that there are more areas that it relates, but it’s the only things I can think of off the top of my head.

    I think that if read LB285 you will see that the state lab has five days to receive the salpme from the time it was collected. If they received it after the five-day period, they are not allowed by law to process the salpme. I’m betting that this is what is happening. No one is planting your DNA, fellas!
