Which of the following statements about testing for communicable diseases is true?

The statement regarding testing for communicable diseases that is true is that tests commanded by the officer are not admissible in court if done under specific situations. This is accurate because there are legal requirements and protections that must be observed when conducting tests for communicable diseases, such as respecting an individual’s rights and ensuring proper procedures are followed. If these procedures are not adhered to, the evidence collected may be deemed inadmissible in court due to violations of constitutional rights or lack of proper consent.

Understanding the implications of when and how these tests can be administered is crucial in the context of criminal procedure. Proper authorizations, such as those from a magistrate, might be required depending on the situation, which can render unauthorized tests inadmissible. Also, the timing of these tests is relevant; they may need to be performed within a reasonable timeframe post-arrest, but there is no hard requirement that they must happen immediately after. Thus, option C accurately reflects the critical balance between law enforcement needs and the protection of individual rights within the judicial system.
