An 83-year-old man was sentenced Monday to six months in jail for scrawling anti-Semitic graffiti in various public locations around Guelph, Ontario, last year. German native Max Mahr also received 40 hours’ community service and two years’ probation. In March, Mahr pleaded guilty to wilfully promoting hatred against an identifiable group, namely Jews. Justice Norman Douglas said Mahr’s behaviour reflected the “mindset which led to the Holocaust” and that his graffiti, which included “kill the Jews” and “exterminate Israelis,” is an offence that will not be tolerated in Canada.
