Is the reason no one scans this cause this one isn't really popular? I just know of this myself and I followed Rurouni Kenshin since elementary school.
The case from 3 years ago was shocking, yes, but I don't think it degrades this manga nonetheless. As long as he keeps the morals in RuroKen straight and not putting his preferences into the manga, I think it's okay. He's still human, after all. Let people have their own weird preferences and fetishes, as long as they don't disturb others.
For those who doesn't know the case, he was arrested for possession of porn DVDs of early teen girls. He purchased DVDs, not the one who did it. Although it doesn't cover the fact that he did say, "I liked girls in the higher grades of elementary school to the second grade of junior high."
If someone were banished just from one sin, I'm sure there won't be any human in this world anymore. That's my two cents.
