Introduction:
The rule that confessions made during police custody cannot be used as evidence against the accused is grounded in the principle of protecting the rights of the accused and ensuring a fair trial. This rule is an important aspect of our criminal justice system and serves to prevent coercion, intimidation, and unfair treatment of suspects during police interrogations.

Presumption of Innocence:
One of the fundamental principles in criminal law is the presumption of innocence, which means that an accused person is considered innocent until proven guilty beyond a reasonable doubt. Allowing confessions made during police custody as evidence can undermine this principle by placing undue weight on the accused's own statements. Confessions can be highly persuasive to a jury, potentially leading to a biased verdict.

Coercion and Duress:
During police custody, suspects may be subjected to various pressures, including physical, psychological, or emotional coercion, to elicit a confession. These tactics can lead to false confessions or admissions of guilt from innocent individuals. Prohibiting the use of such confessions as evidence ensures that the accused's rights are protected and prevents the admission of unreliable and potentially coerced statements.

Protecting Vulnerable Individuals:
Some individuals, such as juveniles, persons with mental disabilities, or those with limited understanding of their rights, may be more susceptible to coercion and manipulation during police interrogations. Excluding confessions made during police custody as evidence helps safeguard the interests of these vulnerable individuals and prevents potential abuse of their rights.

Ensuring Fairness and Due Process:
The rule against using confessions made during police custody as evidence promotes fairness and due process in the criminal justice system. It encourages police to focus on gathering reliable and corroborative evidence, rather than relying solely on a confession. This rule also ensures that the accused has an opportunity to challenge the admissibility and reliability of any statement made during custody, protecting their right to a fair trial.

Conclusion:
The rule that confessions made during police custody cannot be used as evidence against the accused is a crucial aspect of our criminal justice system. It upholds the principles of presumption of innocence, protects against coercion and duress, safeguards vulnerable individuals, and promotes fairness and due process. By excluding potentially unreliable and coerced confessions, this rule helps ensure that the accused's rights are respected and that justice is served.
