On the 29th November 1917, the Prime Minister of Australia (Billy Hughes) was giving a speech on conscription when a man threw an egg at his head, knocking off his hat.

However, what would happen in an alternate timeline where Hughes had had his revolver in his pocket and in a fit of rage shot into the crowd, potentially killing people?
