Preparation for Police Investigation and Interrogation
Police investigation is never an easy experience – even for those who frequently go in and out of interrogation rooms – and of course even more so for average normal citizens who have been summoned for an investigation out of the blue.
In addition to the mental stress that affects the person being interrogated simply by sitting in front of the interrogating police officer, whether it is simply as a warning or not, the discomfort arises from the disparity in knowledge between the knowledge of the police officer and the interrogated person. In other words, the police officer knows exactly which evidence is on the table and what their legal validity is, but as clear and transparent as he/she may appear these details will not be shared with the person being interrogated. These gaps in knowledge are a valuable asset for the interrogator, since in a situation where the person being investigated doesn’t know what the evidence held against them is, if at all, then every word that comes out of their mouth can be the key to their incrimination.
