What people forget is…
Your employer OWNS, from a legal standpoint, ALL of the data on ITS devices.
It doesnt make one shit's worth of difference if its "personal" - your employer OWNS IT, IT IS LEGALLY THEIRS.
Strzok has NO basis to say anything was personal, he has no authority to say they can or cannot be released. The data simply is NOT HIS.
EVERYTHING on his devices are property of the US GOV.
