DNA Technology

DNA has been around for a very long time now; there even has been DNA back in time when

they didn’t have the right technology to use. Years back it was hard to catch a criminal unless

they admitted to the crime because without the proper equipment to run a person DNA there was

no use. I look at it as The Human Identification system is like gold when there is a piece of

DNA. Now it’s our new age in criminal justice system and DNA is revolutionary. The

improvement in this situation is that people that have been accused of crimes and really didn’t

commit them have been released due to the fact that there DNA did not match. Tire impression,

semen, blood, spit, hair, even shoe impression are what experts are using today to catch

criminals, and DNA helps not only with crimes or to catch criminal it’s also helps in paternity

cases as well.

DNA can be admissible in court if it is not found to be reliable. Admissibility is what I call a

status of DNA when it is presented in court cases and it really isn't so much changing. No matter

how the investigators will handle their information the evidence of DNA is always changing. For

an example with Amanda Knox, The DNA evidence was managed in a wrongful manner and

was un cared for with a long period of time so it was unreliable. So It was like saying a murder

suspect was set free. The imports factor to remember is when entering that courtroom all DNA

must remain reliable because in most cases it really speaks for itself.
