EVIDENCE & THE COURTROOM.

Historical police work generated information. Courtroom proof required another level of organization: identifying evidence, connecting it to a person or event, establishing who handled it, and presenting it through legally recognized testimony or records.

RESEARCH LENS

Evidence has a chain and a purpose.

Physical evidence is only as useful as its documented connection to the case.

A police report may mention an item that never became a courtroom exhibit.

Identification evidence can involve observation conditions, memory, lineups, prior exposure, and later testimony.

Laboratory methods, documentation standards, and forensic capabilities in the 1940s–1960s were not the same as today's.

SOURCE STANDARD

Items, testimony, exhibits, and custody claims are described only as far as court or police records support them.
