I think it might be time to switch back to a 12g for home defense, even if im not as good with it, as 30 years in a federal prison doesn't sit well with me.
Keep in mind though, that is only if it is used in the commission of a crime...if you are using it for in home self defense it is unlikely that would come up (assuming everything is legal/NFA).
Still might look bad if the Prosecuter decides to make a case (like you mentioned)...IANAL YMMV
