There's a documentary on youtube on Eto...just place his name in search and it will pop up.

It's in English and subtitled in japanese....I give it an average rating but it's a decent story on not only one of the only japanese OC associates in LCN history, but he's the only asian I know of in the Chicago Outfit's history.

The Eto hit has to be one of the top blundering fuck-up in the history of mob-sanctioned murders. They shot him in the head 3 times and he walked away from it!!
