The prosecution's strongest evidence often comes from DNA, fingerprints, or high-quality video footage that directly links a suspect to the crime, as these offer near-irrefutable proof of presence or involvement, with forensic evidence (like DNA at the scene) being particularly powerful because it's hard to dispute, but a confession or credible eyewitness testimony can also be extremely strong if unchallenged.

What is the strongest evidence in court?

The hardest things to prove in court often involve establishing intent (mens rea), proving causation, or overcoming a lack of physical evidence, especially in cases like sexual assault, white-collar crime, or proving legal insanity, all while meeting the high standard of "beyond a reasonable doubt". Causation, linking an action directly to harm, is notoriously difficult in medical malpractice, and proving a specific mental state at the time of a crime (like insanity) faces significant challenges with expert testimony and jury skepticism.
