This perception of Russia's war in Ukraine as something distant - I've heard that so often here. I get the sense that, for a considerable portion of the population, this is a war they only experience on their TV screen or on their smart phone. In many ways, a virtual war.
Astonishing, really, considering the large number of dead and wounded.
But the killing of a Russian general in Moscow: that is a definite wake-up call; proof that this war is very real and very close to home.
Will it serve as a wake-up call for the Russian authorities?
Probably not. There is little sign of a Kremlin U-turn on Ukraine. Moscow is far more likely to intensify the war.
Just look at the signs.
Reacting to news of Kirillov's killing, the host of a political talk show on Russian state TV blamed Ukraine and claimed that "with this attack President Zelensky has signed his own death sentence".
Former Russian President Dmitry Medvedev said "investigators must find the killers in Russia." He added: "We must do everything to destroy their patrons who are in Kyiv."
Russia's security service says a 29-year-old man from Uzbekistan has now been detained over the killings.
