Why isn't Yukihiro Taguchi in jail?

Don't get me wrong. I don't for a minute think the 31-year-old artist who hails from Osaka deserves to be thrown in the slammer. What he deserves is to be feted at many more exhibitions like the one currently underway at Mori Art Museum in Tokyo's Roppongi district.

But the question remains — both in my mind and that of many of his viewers, it seems. How does Taguchi do what he does, and stay out of trouble? How does he get away with it?
