Is there an evidence custodian required for a Pen register, trap and trace, TIID, or MCTI?

In the context of pen registers, trap and trace devices, TIIDs (Telecommunications Identification Information Devices), and MCTIs (Multichannel Communications Transmission Information), the concept of an evidence custodian is not mandated. These devices do not generate evidence in the same manner as physical evidence collected at a crime scene or data retrieved from electronic devices in investigations that typically require maintaining a chain of custody. The information collected by these tools is often treated as operational data rather than evidence that necessitates strict custodial handling.

In many jurisdictions, the legal framework surrounding the use of these devices emphasizes the importance of the data's collection and its subsequent use. Since these tools primarily aid in law enforcement surveillance rather than in direct evidence collection, there is generally no explicit requirement for a designated evidence custodian associated with the information they gather. Hence, asserting that there is no requirement for an evidence custodian aligns with the operational protocols and legal interpretations surrounding the deployment of these surveillance methods.
