If Joe has been staying straight he shouldn't have much to worry about but, and this only MY opinion, if someone has something on him that he's never been charged with he might end up in hot water again . Time will tell and nobody can beat father time.
That's all I'm trying to say. If he's out of the life, then he should be okay. Unless someone flips and puts an ancient murder on him. That's a different story all together.
