Should you use a suspect photo with a height scale behind the suspect in a photo lineup?

1. Yes, it provides clarity

2. No, it can influence perception

3. Only if approved by a supervisor

4. It doesn't matter either way

The correct answer is: No, it can influence perception

Using a suspect photo with a height scale behind the suspect in a photo lineup can indeed influence perception, making it the most appropriate choice. When a height scale is present, it can lead witnesses to make erroneous assumptions about the suspect's stature compared to other individuals in the lineup, potentially skewing their identification. This can undermine the reliability of the witness's memory and judgment. Maintaining the integrity of the photo lineup process is crucial, as it aims to minimize any external factors that could impact a witness's thought process. The introduction of a height scale might unintentionally suggest to the witness a certain height that the suspect possesses, leading to confirmation bias where the witness may be more likely to select the individual who fits the perceived description rather than relying solely on their memory of the event. In criminal investigations, it is paramount to ensure that all identification procedures are conducted in a fair and unbiased manner. This ensures the accuracy of witness identifications, which can directly affect the outcome of a case.
