Who is authorized to arrest someone suspected of eavesdropping?

The correct answer focuses on law enforcement officers being the individuals authorized to arrest someone suspected of eavesdropping. This authority is rooted in the legal framework that governs criminal activities, including laws concerning privacy and eavesdropping. Law enforcement officers are trained and mandated to enforce the law, including making arrests based on probable cause. They have the necessary legal backing and procedures in place to handle such situations appropriately and protect the rights of all individuals involved.

While private citizens may have the right to report suspected criminal activity, they do not possess the same legal authority to make arrests. Witnessing an act does not automatically grant anyone the power to arrest unless they are law enforcement officers. Additionally, while "anyone witnessing the act" might suggest the possibility of citizen's arrest in some jurisdictions, the regulations surrounding eavesdropping are specific and require law enforcement’s involvement due to the complexity and potential legal ramifications of such actions. Therefore, only trained law enforcement officers have the authority to make such arrests in accordance with established laws and procedures.
