Referring to http://www.latimes.com/world/la-fg-croatia-slobadan-praljak-20171129-story.html (and many similar stories you can google about this incident). This may be somewhat off-topic, but can't think where else to ask.
Note that the guy was a "former philosophy professor". Nevertheless, none of the articles I saw mentioned the (glaringly obvious to me) parallel. So, is he trying to make a statement? Compare himself or his situation to the historical one? Or just trying to off himself as conveniently as possible? Or what?
Edit: By the way, as well as a "former philosophy professor", I just noticed that he was also a "theater director" (and, boy, talk about your "performance art").
