Answer:
Step-by-step explanation:
Yes, forensic science is not 100% reliable. Take finger prints as an example. When police collect evidences at a crime scene, the finger prints are not perfect. They may only a partial image of a finger or they could be blurry. If a suspect's finger prints are to be matched against them, forensic experts have to make a judgement call on whether they match. There are general standards on what is considered an acceptable but opinions of the suspect's guilt due to his skin color or other bias may affect the decision. So forensics is not always reliable.
