Final answer:
It is generally recommended that you do not talk to witnesses before investigators arrive at a robbery scene. Speaking to witnesses before investigators can compromise the integrity of the investigation and potentially influence their testimonies.
Step-by-step explanation:
As the first responder to a robbery, it is generally recommended that you do not talk to witnesses before the investigators arrive. This is because talking to witnesses before investigators can compromise the integrity of the investigation and potentially influence their testimonies.
It is important for investigators to gather unbiased and untainted information from witnesses. By speaking to witnesses before the investigators arrive, you may inadvertently introduce biases or conflicting information that can impact the investigation.
Instead, it is best to secure the crime scene and wait for the investigators to take charge. They are trained to gather information and conduct interviews in a way that maintains the integrity of the investigation.
