Doing nothing will not save you.
Being innocent will not save you.
I am reminded of a scene from the Gulag Archipelago.
Two zeks in camp are talking.
What did you get?
I was sentenced to twenty years under Article 58.
But I did nothing.
Nonsense, if you did nothing you would have only gotten
TEN years...
They’ll eventually arrest you because you didn’t turn anyone else in, and therefore you will be under suspicion.
