WHY IS fingerprint evidence not reliable?

The “Forensic Science Assessments: A Quality and Gap Analysis of Latent Fingerprint Analysis” report makes clear that while latent fingerprint examiners can successfully rule out most of the population from being the source of a latent fingerprint based on observed features, insufficient data exist to determine how …

What are the disadvantages of DNA evidence?

DNA evidence is powerful, but it does have limitations. One limitation is related to misconceptions about what a DNA match really means.

What are the pros and cons of fingerprint analysis?

Fingerprint Analysis Pros Fingerprint analysis provides a way to convict criminals based on hard evidence without dealing directly with more gruesome details often associated with major crimes, like bone and blood DNA evidence.

Can DNA and fingerprint analysis be used as evidence in court?
