Final answer:
The given statement "At the start of interview the investigator in most cases should state, or intimate, that there are independent means to detect any lies" is true.
Step-by-step explanation:
The statement is true at the start of an interview, the investigator in most cases should state or intimate that there are independent means to detect any lies.
This is because informing the interviewee about the possibility of independent means to detect lies can discourage them from providing false information or attempting to deceive the investigator. It can also create an atmosphere of transparency and honesty during the interview process.
