Below is a series of videos and links on this issue. The media so far is doing everything it can to avoid naming the man who decapitated a homeless person he was allowing to stay in his residence, which raises suspicions that its an Islamic name since decapitations is very much more an Islamic thing than a French thing. Unless of course you have a giant veggie slicer. Then its industrial decapitations. But one on one, its generally Islamic.
I suppose this could also be called defenestration.
