Forensic science applies rigorous scientific methodology

Position 1: Consequently, training investigators to handle evidence correctly is as important as developing the analytical technologies themselves.

Position 2: Trace evidence such as fibres, glass fragments, and hair can link a suspect to a location even when no direct witnesses are present.

Position 3: Despite its accuracy, forensic evidence must be collected and preserved according to strict chain-of-custody protocols; otherwise, courts may deem it inadmissible.

Position 4: Forensic science applies rigorous scientific methodology to the analysis of physical evidence collected from crime scenes.

Position 5: DNA profiling has proven especially powerful, as it can identify an individual from a single cell left on an object with remarkable statistical certainty.
