How conclusive is DNA fingerprinting evidence?

In: Criminal Law [Edit categories]

Answer:

DNA evidence is very conclusive and some say 99% accurate, however it is possible to challenge it based upon faulty collection and/or faulty lab techniques. All evidence can be contaminated by faulty collection and preservation methods and it leaves the evidence open to challenge. One key component to preserving any evidence is maintaining a secure chain of custody of any collected evidence. from the time of collection to the end of the case in court every movement of the evidence must be documented.
