Dylan Klebold's autopsy report says "Present on the left boot was a red star medallion containing a sickle and a hammer."
The hammer and sickle pin that he's wearing on his boot was a symbol used by the U.S.S.R. and was worn for more of a fashion statement by Dylan than for ideological reasons
Dimitrios Pagourtzis (Santa Fe school shooter) wore it on his trenchcoat. He wrote on a caption in his instagram: "Hammer and sickle = Rebelion"
