Then why is Ghislaine still alive and in jail?
“why is Ghislaine still alive”
Maybe she was the one smart enough to have a well hidden deadman switch.
That's really two questions, isn't it?
Why still alive? Because not all the evidence is accounted for, and there may be a dead man switch.
Why is she still in jail? Both to protect her and to pressure her to give up said evidence.
It's a question of trust on both sides. TPTB need to believe Maxwell won't talk or leak evidence on certain people. I don't know how anyone could guarantee that while she lives.
Maxwell needs to believe she won't be immediately killed after all evidence is secured or destroyed. I don't know how anyone could guarantee that, either.
We may think that, but we do not know it.
