Kostopoulos was buried in the town of Kirra where he grew up.[16] Since 2018, people organize yearly marches in Athens to commemorate Kostopoulos' death and call for justice against his killers.[2][17][18] The slogans "Zackie lives, smash the Nazis" (which rhymes in Greek: Η Ζάκι ζει, τσακίστε τους ναζί) and "cops, TV, neo-Nazis, all the bastards work together" (μπάτσοι, τιβί, νεοναζί, όλα τα καθάρματα δουλεύουνε μαζί) were chanted at events across the country.[9][19]
