In January 2004, he vandalized the art installation "Snow White and The Madness of Truth" by Israeli-born Swedish artist Dror Feiler and his wife Gunilla Sköld Feiler. The installation took advantage of the reflecting pool at the courtyard of "Historiska Museet", that was highlighted and filled with red liquid signifying blood. The work further consisted of plaques with poetry on the surrounding walls and music by J.S. Bach. Well-lit on the surface of a basin: a styrofoam boat, displaying a portrait of the Palestinian suicide bomber Hanadi Jaradat, who had perpetrated the Maxim restaurant suicide bombing a few months earlier, on one side and the word "Snövit" ("Snow White" in Swedish) written on the backside. Mazel pushed some lightstands into the pool, causing a short-circuit and disabling the light, and then told Feiler that: "This is not a work of art. This is an expression of hatred for the Israeli people. This has glorified suicide bombers". Further he said to the press that the piece constituted a "complete legitimization of genocide, the murder of innocent people, innocent civilians, under the guise of culture". Feiler rejected charges that their intention was to glorify suicide bombers and accused Mazel of "practicing censorship". Feiler, who would play at the opening ceremony, refused to begin until Mazel left. Despite trying to explain himself, Mazel was asked to leave and escorted off the premises by museum security. The Swedish Foreign Ministry summoned him to ask for clarifications over the incident.
