Sanctioned by the courts and taught in police manuals, deceptive tactics are employed by virtually every police department across the country. Officers seeking to elicit a confession will routinely lie to suspects about the evidence and make statements that imply leniency. While effective at times, deception is ethically dubious and can result in severe consequences for suspects. The United States is an outlier in allowing police to deceive suspects, as the practice is prohibited or highly restricted in most peer nations, including England, France, Germany, and Japan.
First, deceptive interrogation tactics frequently induce false confessions, which are a leading cause of wrongful convictions in the United States. Further, the acceptability of lying to suspects during interrogations seems to encourage deception in other, more troubling contexts. Research shows that testimonial lies, such as perjury in court and falsifying police reports, are commonly employed by officers to secure convictions and circumvent constitutional protections. While such practices remain illegal, testimonial lies are rarely identified or punished. As a result, the justifications and skills cultivated through deceiving suspects in interrogations naturally bleed over into other police work.
