Question

Quizplus · Accepted Answer

Abusive police interrogations are most frequently dealt with through videotaping, which provides an objective record of what took place during the interrogation. This can help prevent abuses and protect the rights of the accused. Interrogations conducted in public or in the presence of a lawyer can also help prevent abuses, but these measures are not as commonly used as video recording. Multiple officers may be used in an interrogation for safety reasons or to aid in questioning, but this does not necessarily prevent abusive tactics.
