In which situation would you most likely need to obtain a court order?

Obtaining a court order is particularly important when using electronic surveillance because such actions typically involve the interception of private communications or monitoring individuals without their knowledge. In many jurisdictions, including Missouri, engaging in electronic surveillance without appropriate legal authorization is a violation of privacy laws and can lead to serious legal repercussions.

A court order serves as a legal confirmation that the surveillance is justified, typically requiring evidence that there is probable cause to believe that a crime is being committed or that such surveillance is necessary for an investigation. This process is essential to protect individuals' rights under the Fourth Amendment, which guards against unreasonable searches and seizures.

In contrast, situations like conducting casual interviews or notifying the police about a crime usually do not require a court order. Collecting physical evidence may also not necessitate a court order if it is obtained lawfully and without infringing on any individual's rights, such as through a lawful search warrant or with consent. Hence, the act of conducting electronic surveillance stands out as needing a court order to ensure legal and ethical compliance.
