Following an incident of alleged vandalism at an interactive digital art exhibition, eyewitness statements have been shown to be highly unreliable.
Immediately after a loud crash and a sudden blackout in the main gallery, visitors were evacuated to a holding area where many chatted and compared accounts on a temporary messaging group. When interviewed later by security staff, several visitors reported high levels of anxiety, recalling a "hissing sound of aerosol paint" and claiming they saw a "masked activist in a black hooded sweatshirt spraying a valuable canvas." A local suspect was subsequently detained.
However, forensic analysis of the gallery's high-definition thermal security footage revealed a completely different reality. The person in question was actually an authorized gallery technician wearing a bright blue knit cardigan, who was merely holding a pressurized plastic water bottle to mist some nearby tropical plants. The loud crash was caused by an unstable display monitor falling over due to a loose bracket, and the "hissing sound" was a steam radiator releasing pressure. The defense lawyer demonstrated that the initial security guards had asked repetitive, leading questions, such as "How fast was the activist moving when they brandished the spray can?"
Evaluate how suggestions for improving the questioning of witnesses (such as the Cognitive Interview) could be used to enhance the accuracy of eyewitness testimonies in relation to this incident.
