We need a criminal DNA database as soon as possible. This database would save many lives and solve
many crimes and cold cases. Most
criminals do not understand forensic science and inadvertently leave trace
evidence behind at crime scenes. A
national criminal DNA database would also help different agencies work together.
DNA testing would have a great impact on solving crimes, and I think they already do. This type of testing helps to put away murderers and rapists. It may be the most important part of criminal investigations. It would be helpful to have a database for DNA so that criminals don't have to even be preset to get the cells needed to prove their guilt.
Yes, I agree, DNA databases would be good, but what if someone turned out to be falsely accused? Then they'd be in that database even though they didn't commit that crime. False accusation would be the flaw of that system, and even though there are many advantages of DNA databases, you have to think of the flaws of the infrastructure too.
