An argument in Russia over philosopher Immanuel Kant devolved into less subtle tactics when one debater shot the other.
The row in a small store in Rostov-on-Don deteriorated into a fistfight. One man then pulled out a small non-lethal pistol and fired repeatedly.
The victim was hospitalised with injuries that were not life-threatening. The weapon fired plastic bullets or blanks. It was not clear which of Kant’s ideas may have triggered the violence.
