4. D looks right.

To determine the correct answer to question 3, we need to understand what each option means:

A. Exigent circumstances: This refers to situations where law enforcement needs to act urgently to prevent harm or evidence destruction.
B. Public safety: This refers to circumstances where law enforcement actions are justified to protect the general public.
C. Emergency: This term generally refers to immediate and urgent situations that require immediate action.
D. Impracticality: This refers to situations where it is not feasible or reasonable to adhere to certain legal requirements.

In this case, given that the question is asking about an exception to Miranda warnings when a threat exists to third parties, the most appropriate answer would be B. Public safety.

To determine the correct answer to question 4, we need to understand what each option means:

A. Reliable: This means that the results from the identification procedures are consistent and trustworthy.
B. Accurate: This means that the results from the identification procedures are correct and free from errors.
C. Admissible in a criminal trial: This means that the results from the identification procedures can be presented as evidence during a criminal trial.
D. All of the above: This means that the results from the identification procedures cannot be considered reliable, accurate, or admissible in a criminal trial.

In this case, the correct answer is D. All of the above. When identification procedures violate constitutional provisions, the results of those procedures cannot be considered reliable, accurate, or admissible in a criminal trial.
