Mayor Bill de Blasio rebuked an open letter published in newspapers on Tuesday and paid for by a police union in an attempt to dissuade the Democratic National Convention from coming to Brooklyn in 2016.
The Sergeants Benevolent Association, which is currently negotiating with the city for a new labor contract, bought full-page ads in both the New York Times and New York Post to accuse de Blasio of taking the city back to days of high crime that should disqualify Brooklyn as a safe host for the convention.
"It's clearly an effort to advance their position in terms of contract negotiations," de Blasio told reporters at an unrelated event. "And I think it's an irresponsible act on their part. It's fear-mongering to try and benefit their own position in labor talks."
The ads said that de Blasio "has not earned the right to play host to such an important event" and that his policies have left the city "lurching backward to the bad old days of high crime, danger-infested public spaces and families that walk our streets worried for their safety."
Tuesdays ads are only the latest conflict between the union and de Blasio administration. SBA President Ed Mullins has levied a series of criticism against the city's response and defense of the NYPD after death of Staten Island man Eric Garner while in police custody.
Mullins has also long attacked de Blasio's positions on stop-and-frisk as cause for low morale among officers.
Earlier this month, local leaders, including Police Commissioner Bill Bratton, unfurled a blue carpet at Brooklyn's Barclay's Center to convince the Democratic National Committee to pick the outer borough as home for the next convention.
"I think when you leave you’ll understand that we are the city where you should be for the upcoming convention – that the NYPD is part in parcel of this city’s efforts to ensure that it will be safe, will be secure, and that the transportation issues will be facilitated," Bratton told the invited DNC committee.
"People who care about New York City, who want to see New York City move forward, want to see New York City prosper, should be supporting our convention bid." de Blasio said on Tuesday.
