Don't think so, it's basically like lock picking a suspect's apartment with a warrant. What is found should be valid evidence, no?
Law enforcement can break the door or call a locksmith and pay him for his service. In this case Cellebrite's the locksmith.
That seems reasonable, but usually investigators would be on the scene while the locksmith works. If the process is a black box that happens while the device is in Cellebrite's possession isn't it more like calling up the locksmith from the precinct and saying "hey, could you open up the apartment at this address and call us when you're done? Don't go inside or touch anything though, thanks!" What prevents Cellebrite employees from planting or deleting evidence after the device is unlocked and before returning it? What guarantees are there that Cellebrite's unlocking process doesn't intentionally or unintentionally modify some other aspect of the device? Scouts honor? What if their process is to just flash a new rom filled with child porn and no passcode then skip merrily to the bank to cash their checks?
Yep, I understand that. I don't think that was posed as a problem in the Italian case I know of, although I think that in the U.S. rules on the chain of custody are stricter, indeed. That's a good point.
