The effectiveness of a show up is influenced by several factors that directly relate to the conditions and context of the identification procedure, such as the time elapsed since the incident, the number of witnesses called, and the manner in which the show up is conducted. These factors can greatly affect a witness's ability to accurately identify a suspect.

When considering the background of the offender, while it may provide some context to the witnesses, it is generally not a critical factor in the immediate effectiveness of the show up itself. Factors like how recently the witness saw the suspect, the setup of the identification process, and how many witnesses are available to corroborate the identification all play a direct role in ensuring that witnesses can give reliable testimony. Therefore, focusing on the characteristics or background of the offender does not usually impact the immediate effectiveness of the identification process in a show up scenario.
