This questioning is called interrogation, information-gathering activity of police officers that involves the direct questioning of suspects. There are different types of interrogation styles that has been used before in the past years. Physical abuse, officers beating suspects until they confessed to the crime. This method has been frowned upon, because suspects would confess only to stop the pain. Another type is inherent coercion, fall short of physical abuse, but nonetheless pressure the suspects to reveal information. Officers would not physically abuse the suspects, but placed the suspect in a hostile atmosphere. Suspects could be sitting under a blinding light for hours and just being stared at.

    In such a case, the police would be justified to use brutal force as a way to protect them. However, this was not the case on the four cases identified above. The officers must also only use brutal force when they are pursuing a dangerous criminal who needs to be brought to justice by all means. If the suspect is a wanted criminal, the police can use brutal force as a way to apprehend the criminal, even if he or she is not armed at the time of the encounter. For instance, an officer can use such force on a murder suspect who has been hiding from the police for a long time, even if the suspect is not armed, as long as the criminal tries to use other ways such as running away to avoid arrest.…

    What the suspect leaves behind or purposely doesn’t leave behind, tells law enforcement a lot about their distinct personality. For example: crime scenes that are disorganized with evidence left behind may mean that they’re psychotic and unintelligent while organized scenes point to a more intelligent offender who has carefully plotted his attacks and taken care of evidence.
