New York City's rank-and-file police union is urging cops to tell Mayor Bill de Blasio not to attend their funerals in the event that they are killed in the line of duty.

The Patrolmen's Benevolent Association posted a link on its website telling members not to let de Blasio and City Council Speaker Melissa Mark-Viverito "insult their sacrifice" should they be killed. The union posted a “Don’t Insult My Sacrifice” waiver officers can sign requesting the two politicians not attend their funerals due to their "consistent refusal to show police officers the support and respect they deserve."

The waiver says that attendance of the two elected officials “at the funeral of a fallen New York City police officer is an insult to that officer’s memory and sacrifice.”

The New York Post reports the mayor and council speaker are calling the effort "deeply disappointing."

"Incendiary rhetoric like this serves only to divide the city, and New Yorkers reject these tactics," they said in a joint statement.

Sources told the Post the union is angry that the mayor did not show more support for the NYPD after a grand jury decided not to indict the officer involved in the death of Staten Islander Eric Garner.

In a press conference about the grand jury’s decision not to charge the officer, de Blasio announced that he had warned his 17-year-old, mixed-race son, Dante, to be careful around police officers, which caused PBA President Patrick Lynch to claim de Blasio had thrown NYPD officers “under the bus.”
