Warning: This story contains offensive language, discretion is advisedAs the former head of homicide for Toronto police, Hank Idsinga was instrumental in solving some of the city’s most notorious crimes.His new memoir, ‘The High Road: Confessions Of A Homicide Cop’ delves into many of those gripping tales.But the seasoned cop didn’t just stare down stone cold killers. Idsinga, whose grandfather was murdered in the Holocaust, also claims he stared down “racism and dysfunction” within the ranks at Toronto Police Service (TPS), outlining instances of alleged antisemitism that left him “feeling physically ill.”Idsinga will discuss his bombshell memoir with Faiza Amin on CityNews Channel at 12 p.m. on Wednesday. Watch here.In the book Idsinga emphasizes that “the members of the Toronto Police Service are overwhelmingly good, decent people…” but says the police force is not immune to the “personal biases that exist in society,” including antisemitism, anti-Black racism, misogyny and homophobia.“As long as they exist in society, they will continue to exist in the police service too,” he wrote. Idsinga said he’s seen evidence of “vile racism in the uppermost ranks of the police service.” In one instance, Idsinga said a positive video was shared internally about a divisional officer.“I happened to walk up when a senior officer was watching it,” he recalled. “The senior officer hit pause, looked at me, and said, “The only reason he gets away with this is because he’s a f*****g Jew.”He says the same senior officer, who went unnamed, also referred to a kosher barbeque as a “Jew-q,” a comment he says he “chalked up to a bad attempt at humour.” “They had no idea about my heritage,” he added. When members of his office had to do a presentation to a lawyer at police headquarters, Idsinga wrote that the same senior officer remarked, “I can’t believe we have to pander to this f*****g Jew.”“It’s amazing how a few bad apples can absolutely destroy the reputations of an organization that numbers in the thousands,” he wrote. The explosive allegations did not go unnoticed by the Toronto Police Service. Multiple media reports say TPS wrote the retired detective a letter, and sent uniformed officers to his home, in attempts to secure an interview with him about his claims.Idsinga has so far refused the invitation, telling the Toronto Star “I’ll let the book speak for itself.”Toronto Police Association (TPA) president, Clayton Campbell, addressed the book’s allegations in a recent radio appearance.Campbell stressed that he didn’t question Idsinga’s experiences, but said they represent only a small minority of officers.“Our members every day do the best they can and protect anybody and the vast majority would literally put their lives on the line to protect others, regardless of where they come from, what they look like, what religion they are. They do the best they can.”
