A Hamilton police officer, back at work after he was investigated for sharing racist and extremist content online, is again displaying a sticker “associated with white nationalist extremism” on his vehicle, a community group says.

The Hamilton Anti-Racism Resource Centre (HARRC) says that in February, a concerned community member photographed Const. Renato Greco’s personal Jeep sporting a decal featuring a Knights Templar crest, a symbol “appropriated by some white nationalist and neo-Nazi groups.”

The sticker features a phrase which was also the title of a 1960 pamphlet by George Lincoln Rockwell, who founded the American Nazi Party, HARRC said in a post Monday.
