What is the best approach to questioning during an investigation?

The principle that a suspect is innocent until proven guilty is foundational to investigative practices and the judicial system as a whole. This approach emphasizes the importance of impartiality and fairness during an investigation. It ensures that investigators approach each suspect with an open mind and without bias, allowing room for truth and the possibility of innocence.

By adhering to this principle, investigators can build their cases on solid evidence rather than preconceived notions or assumptions about a suspect's guilt. This method promotes the integrity of the investigation, protecting the rights of individuals and maintaining public trust in the investigative process. It encourages thorough and unbiased questioning to ascertain the facts, thus allowing investigators to discover the truth without leading questions or pressure that might result in false confessions or unreliable information.

In contrast, the other options lean towards presumptive reasoning that could compromise the investigation's integrity and outcome. Recognizing a suspect's innocence creates a fair framework for conducting inquiries that uphold legal standards and protect individuals' rights while seeking the truth.
