ed ovviamente si sono sparati, se il tizio non avesse avuto la pistola avrebbero fatto a pugni, invece avevano la pistola sia il perpetratore che il difensore ed han rischiato di ammazzarsi, qui in italia sarebbe stata questione di occhi neri visto che non siamo tutti armati.

A man with a handgun stopped an angry partygoer who opened fire at a party early Sunday morning in Glendale, Arizona.
According to local media, the aggressor, who has only been identified as a 27-year-old male, was kicked out of the party after he got into an argument with several guests. He returned a short time later armed with
a rifle and started firing off rounds outside of the home.
But when he turned the rifle on the party guests, another man, who has also only been identified as a 39-year-old male, pulled out a handgun and shot him.
When the police arrived, they found the 27-year-old suffering from a gunshot wound and transported him to a local hospital where his injuries are said to be life-threatening.
