Two very obvious points,
1) he isnt going to be honest, it's not in his character, regardless of why. Continuing to expect him to be completely truthful is contrary to his nature and therefore a waste of your time.
2) I have read all the docs that are available, not because he sent them, because I pulled them myself. I'll be kind and answer the legal question you already know the answer too; yes he has cooperated in some manner, to what extent fully, well that is not able to be viewed with my limited capacity.
The best and safest action for all, is to avoid any and all contact with the man. That being here on the boards, or anywhere else.
Biggerben69 has briefed you all well, nothing more really needs said. Regardless of what the sealed docs say, he is bad news and a security risk for anyone in contact with him.
Stay safe brothers,
