Final answer:
Video surveillance by private parties such as private investigators can implicate the Fourth Amendment when certain conditions are met.
Step-by-step explanation:
Video surveillance by private parties such as private investigators can implicate the Fourth Amendment under certain circumstances. The Fourth Amendment protects individuals from unreasonable searches and seizures by the government, and it applies to both public and private actors when they engage in activities that would be considered a search under the Amendment. For example, if a private investigator uses surveillance equipment to monitor a person's activities in their home, without their consent or a valid warrant, it could be considered a violation of the Fourth Amendment.
