Generation and Assessment of Alibis

An initial step in many law enforcement investigations is to ask potential suspects to provide an account of their whereabouts during the time the crime took place (i.e., provide an alibi). The ability of investigators to assess the veracity of alibis effectively is crucial to resolving cases successfully and avoiding miscarriages of justice. Research within the ALERT Lab is measuring various aspects of the alibi assessment process, as well as assessing the ability of innocent suspects to generate believable alibis.

Improving Investigative Interviewing Procedures

The ability to gather detailed and accurate accounts from interviewees is vital for the successful resolution of law enforcement investigations. Investigators are in need of interviewing tactics that are both science-based and ethical. Research within the ALERT Lab is assessing the effectiveness of various interviewing procedures in increasing the amount and quality of recall from interviewees

Comprehension and Utilization of Interrogation Rights

Individuals in Canada that are detained by the police and facing an interrogation are afforded several legal rights for their protection. Legislation and case law has dictated that detainees must understand these rights fully in order for any subsequent disclosure to be admissible in court - meaning that comprehension of interrogation rights is important both for detainees and police organizations. Research within the ALERT Lab is identifying ways to increase the comprehensibility of interrogation rights.
