You can be DF for any sort of disobedience for which: 1) you are not repentent, 2) you confess or there are two witnesses. If there are two witnessess to you owning/reading the books then you've promoted apostacy to those two people. When it gets to the three Commmitty members, then you've exposed five people to such evil things.
You'd better be seen to be a rock solid JW, have an excuse, and repent like crazy. If it's well known in the congo that you have them (like after the elderettes get to work telling everyone), you fate is nearly sealed but you may still getaway with a public reproof.
Good luck - best just to fade away IMO.
