Believe it or not: it is possible to read CoC and become a baptized witness thereafter.
If you are raised in a witness family with roots back in the 30s there is nothing unheard of. Even 1975 was awaited with some kind of skepticism. So if you have such a back history you want to make sure of what you do before you get baptized, as the WTS encourages one to do. Thus one comes across unbiased information at the public library which contains information based in part on apostate literature. Knowing both sides one is able to make an informed decision, which can still be to become a JW, although you know of the inconsistencies and imperfections.
But to this day I have not found a sound alternative.
