The quality gradient

"In assassinations, there are gradations of respect," said Gladki. "The lowest is strangling. If you strangle someone, it is a sign of severe disrespect." Using a pistol, he said, is "50/50" – kind of an OK, but not brilliant way to be killed. "And then there is the Kalashnikov. To be shot by a Kalashnikov assault rifle is the ultimate form of respect. It is a very good death for a Russian."
