Wrongful convictions in Canada are a very sensitive and troubling topic that has raised concerns about why individuals are wrongly convicted. When Canadians read about wrongful conviction cases, like those of Guy Paul Morin, Rubin Carter and David Millguard, it often undermines their confidence in the criminal justice system. Tunnel vision, use of questionable DNA evidence and misidentification by eyewitnesses are the three leading causes of wrongful convictions in Canada. Recognizing and addressing these concerns has led to a reduction in cases of wrongful convictions in Canada. Tunnel vision is a significant factor contributing to wrongful convictions. Tunnel vision occurs when police officers focus on a particular subject. One of the leading factors in wrongful convictions, tunnel vision, has been recognized by a psychologist as a human tendency to quickly convict a suspect so that society feels safe. Although tunnel vision is considered a natural instinct, it can convict innocent individuals and weaken the criminal justice system. U.S. Court of Appeals Judge Jerome Frank explored the causes of wrongful convictions and noted that in 36 cases, tunnel vision was a significant factor in the conviction of innocent individuals. As demonstrated, tunnel vision is a prevalent factor and can affect cases, leading judges and juries to convict the wrong suspects. However, the human tendency towards tunnel vision is a distinctive feature of an individual's psychological characteristics. Psychologists view tunnel vision as the product of cognitive biases. These natural biases are why tunnel vision is common, even among respected law enforcement and honest justice systems. Although tunnel vision is a common natural tendency, it can be distorted and lead to the conviction of innocent individuals. In situations where a high-profile case is under pressure from victims, the community, media, and police supervisors often cite timeliness as a primary factor during the investigation. case. Police officers have human tendencies when trying to achieve the overall goal of justice when solving a case. Tunnel vision is often the result of police officers having a narrow theory about a suspect, drawing early conclusions about who is responsible, and ignoring evidence that indicates the suspect is innocent. These factors that contribute to a narrow view of the criminal justice system are the cause of the narrow view that results in wrongful convictions of innocent individuals. Another factor associated with wrongful convictions is the misidentification of eyewitnesses. The Innocence Project identifies eyewitness misidentification as the single most important factor leading to wrongful convictions. Misidentification of an eyewitness is often a mistake due to the fact that witnesses are under great pressure, witnesses focus more on the weapon than the attacker, and police procedures when they receive a victim identification statement.
