"blood on your hands, you've got blood on your hands, you murdering bastards, you've got blood on your hands" works better imo.Our vocal display should be enough to get the moral message across. Live on terrestrial TV with 40k singing "we know what you are, we know what you are, murdering b@stards, we know what you are".
Also think a Jamal Khashoggi song would be appropriate.
We need some song coordination for this match to be all singing from the same hymn sheet.
