I’m not so sure he’s much of a security risk, unless he is still in possession of sensitive documents. I sincerely doubt he is capable of remembering anything in the way of valuable secrets. Anyways, even if he did, any adversary would be daft to trust he remembered correctly.
Strict adherence to sentencing guidelines actually would see him jailed on his current convictions. If he isn’t given some kind of imprisonment it will be because the judge was afraid of the aftermath.
