When must a common pleas judge be informed of mobile tracking device activation?

The correct answer is that a common pleas judge must be informed of mobile tracking device activation within 72 hours. This time frame is significant as it ensures oversight and accountability in the use of mobile tracking technologies. Timely notification to a judge is a critical aspect of maintaining legal compliance and protecting individuals' rights under privacy laws.

This requirement reflects the need for judicial oversight over law enforcement practices, particularly when it involves surveillance techniques that could infringe on a person's privacy. The 72-hour window allows law enforcement to conduct necessary tracking activities while ensuring that there is swift accountability and oversight from the judiciary.

Understanding the time frame in which this information must be provided helps to emphasize the balance between effective law enforcement and the protection of civil liberties.
