Which of the following is correct regarding hostile witnesses?

A) They should be interviewed as early as possible in the investigation.
B) They should be interviewed in the middle of an investigation.
C) They should be interviewed at the end of an investigation.
D) It does not matter when they are interviewed.

Interviewing hostile witnesses as early as possible in an investigation is crucial. This approach allows investigators to gather critical information while memories are fresh and before witnesses can align their stories with others or be influenced by external factors. Early interviews also help in identifying inconsistencies or additional leads at the outset, which can be pivotal for the direction and effectiveness of the investigation.
