I’m not sure it’s in those exact terms, but I think there were a few cases with high levels of preparation. Ended up being ruled as suicides anyway by the courts and the media. Not saying they’ll always win, though. But their idealogical power is not to underestimate.

A minister in my country was deemed to have committed suicide by drowning in a 50cm body of water. Strangely enough, all witnesses have committed suicide too just before being heard by the courts.

And it worked. Everybody know it wasn’t a suicide, but it changes nothing for those responsible of the murder.
