In reference to the cell phone technology the Sheriff's Office is attempting to purchase from Cellebrite on a COVID grant.
From my cursory review, it appears this is to extract data/evidence off of a phone, with a search warrant, when that phone is in law-enforcement possession related to an investigation. That data could include your contacts, travel history, calls, and texts which equates to contact tracing but not in real time.
In regards to real time contact tracing, that is a different software application where you don’t lose your phone to be traced but rather it’s done through the service providers unknown to you and with or without your consent.
These are two completely separate extraction methods and uses.
This is where having experience in the profession is beneficial. You know what you’re talking about in regards to the tools that are used for investigations, versus pushing the PANIC button.
