Mandy volunteered in a month-long sleep study at the university last year. She was asked to participate because of her unusual sleep habits and neurological history. Part of the sleep study included her sleeping in a room inside the lab for the entire month. She was videotaped while she slept. Now, 13 months later, police are trying to charge Mandy with possession and use of illegal drugs. It turns out she was using drugs during her stay at the sleep lab. Her drug use was recorded in the lab videos. She's not sure how or why the police saw the videos. She knew she was being videotaped, although she was told it was only for the study and that no one outside the lab would view the footage.
Would the video evidence be helpful in proving the case? (Answer in one to two sentences. Explain your reasoning.)
