According to Yomiuri, members of Fukuoka Prefectural Assembly have been accused of spending public money for the policy affair research on irrelevant books including porn novels. Among them, Takahashi Masanari, 52 year old assemblyman, was found to have purchased Toaru Majutsu no Index vol.19 and Iruma Hitoma's light novel Denpa Onna to Seishun Otoko vol.3. The assemblyman made an excuse that it was a legitimate expense to research the current trend of the world.
"“Religion, the dominion of the human mind;
Property, the dominion of human needs; and
Government, the dominion of human conduct,
represent the stronghold of man's enslavement
and all the horrors it entails.”"

I imagine they bought lots of other books and materials for cultural study as well, but there's really no reason to research manga at the assembly level to begin with (and I bet they get paid to read them at work while doing their research lol). If they honestly need this reasearch, it can be done by a third party (otaku advisor bwahaha) and summarized for them.
btw, the story also says that they are refuting the porn novel buying, since he never remembers the particular book and the way the receipts were matched might be mistaken... but I bet it was just bought by mistake.
