USA government agencies, (police, courts, etc) are prohibited from downloading / installing 3rd party software to their department issued laptops & computers by their IT departments.
That's why investigations, and court litigation involving evidence is stored, transferred, and viewed on physical media like VHS tapes & DVDs & CDs.
When I was in government service I was prohibited from taking photographs of evidence with my agency issued iPhone, and had to use Digital Camera that stored the photos on those little tiny CD's to be submitted into evidence.
This is because if defense lawyers found out we took evidence photographs, or videos with our iPhone, they would subpoena the actual iPhone into evidence, and we would loose it for however long the case was.
