They might blame you but that doesn't mean they have any proof that you did anything. If they did, they would likely have already told you, and you'd be arrested. But for sure, don't say anything to anyone at that company anymore, retain a lawyer, and go through all the details with them. If you aren't terribly worried, you could always get a lawyer when you need to (if charges arise, or if you are sued, which I honestly doubt). It doesn't sound like the lawyer will be able to do anything unless they do something first, so I don't see any big reason to jump the gun. Don't try to sue them or take any action against them, that's too high risk for the same reasons. It sounds like your company is quite a piece of work, but if they are disorganized as you say at so many levels, it just sounds like them using you as a scapegoat. For a few months after someone leaves, everyone blames that person anyway - they can't fight back. That part is normal.
