Yeah most of the other evidence will come from the 100 million Sky chats, but that's a complicated investigation and several trials related to Sky are already difficult because judges can't always value that evidence. With all that crypto shit it's a new ball game.
I read that some courts won't accept SKY as evidence.
Yep there have been cases with Sky-ECC evidence in court dismissed, but in other cases courts found the evidence reliable.
Operation Sky ECC is also delayed in Belgium due to 'unreadable CD-ROMs' and lack of proper computers.
