"Our police departments are normalizing the use of sham sympathy and unabashed deceit with social reinforcement from fellow officers who, with the blessing of the courts, take their cues from the same playbook. But unlike human suspects, the habit of lying can’t be confined within the solid-block walls of an interrogation room. A number of academics, relying on studies from the field of psychology, have warned that we are turning lying into a learned social behavior that becomes more routine with each successfully-coerced confession. Positive feedback from each “victory” in the interrogation room inspires police to deploy the same techniques in new environments. While deception is, by its nature, difficult to measure, evidence suggests that police not only lie outside the interrogation room, but lie often: even under oath when it constitutes perjury.

But no empirical data suggests that policing would be crippled if police officers could no longer lie to arrested suspects. Nor is it a universal practice. British courts regularly exclude confessions obtained through the use of deceit, and Germany places strict limitations on the use of deceptive tactics in interrogations. Not only do both countries enjoy lower rates of crime than the US, early data shows that new, non-deceptive interrogation techniques employed in the UK not only produce a high volume of confessions, but fewer false confessions as well."
