It is a well-known and documented fact that the state police executed and tortured Hungarians for years during the communist terror of the early 1950s. The state police were so despised that the freedom fighters exacted their revenge on them. You can see many photos in this video showing dead state policemen. The music to this video is by the Hungarian rock band Kárpátia and the song is called "Neveket akarok hallani" (Names I want to hear). The photos at the end of the video show the most despised Hungarian communist leaders.
