hmm.. all you got are some pictures. and a very secretive culture that does what it is told. just watch '47 Ronin' to see the depth of rule following possible, and how far you can get people to go, even when they do the right thing, to actually intentionally... willingly, kill themselves.

so anyway, ya, i think shit like that can, did, does happen.

seems like a receipt for deceit.
