What could make eye witness testimony more accurate and helpful?

The video discusses lineup procedures used by police, focusing on double-blind and single-blind lineups. In a double-blind lineup, neither the witness nor the officer knows the suspect's identity, reducing bias. In contrast, a single-blind lineup is where only the witness is unaware of the suspect, which is the standard practice in the US. The video highlights the potential for non-blind administrators to unintentionally influence witnesses by giving cues, such as tapping on a suspect's photo, which can lead to increased suspect identifications. The goal is to avoid unfair systems where police inadvertently suggest who the witness should identify.
