Answer :
The rule that is important to follow during investigative questioning is the Davis rule. This rule states that law enforcement officers must inform a suspect of their Miranda rights before interrogating them, ensuring that the suspect is aware of their rights to remain silent and have an attorney present during questioning.
Following the Davis rule is crucial in investigative questioning to protect the suspect's constitutional rights and ensure that any evidence obtained during the interrogation is admissible in court. Failure to adhere to the Davis rule can lead to the exclusion of incriminating statements or evidence gathered during the questioning process.
In contrast, the "14-day break-in-custody" rule refers to the amount of time a suspect can be held in custody before being released or formally charged. The Bruton rule deals with the confrontation clause in the Sixth Amendment regarding the admission of statements by a non-testifying co-defendant. The 80-20 rule is not specifically related to investigative questioning but is a principle that suggests focusing on the most important tasks that yield 80% of the results.
Therefore, in the context of investigative questioning, it is essential to prioritize following the Davis rule to ensure that the rights of the suspect are respected and that the evidence gathered is admissible in court.
