Downtown Brooklyn community leaders and elected officials gathered Monday to condemn the latest in a series of sporadic incidents targeting Jews in the area.

Last Wednesday, small slips of paper with "Kill Jews" written on them were scattered around Sixth Avenue in Park Slope.

"[It's] disturbing that we are still seeing despicable incidents of intolerance such as the cowardly, anti-Semitic words of hate found in Park Slope," said Brooklyn Borough President Marty Markowitz, who spoke at a press conference at Congregation Beth Elohim.

The press conference was organized by the Jewish Community Relations Council (JCRC) of New York.

"Statements, symbols or acts of hate are simply unacceptable as they tear at the very fabric of our society," said Bob Kaplan, director of CAUSE-NY, the JCRC's center for community and coalition building. "We need to ensure that the voices of inclusiveness and understanding are our guides in the face of those who seek to destroy our American values."

Similar notes were discovered in the same area in October and in other adjoining neighborhoods the previous month. In 2007, synagogues and homes in the Brownstone Brooklyn area were defaced with anti-Semitic graffiti.

Park Slope resident Karen Guilbert told The Brooklyn Paper, a local weekly, that she found the latest notes between Fourth and Ninth streets last Wednesday. When she pieced the sliced papers together, she found a flyer for a taxi driving school on the other side.

The NYPD's Bias Crime Unit is investigating, although a police source said any suspect was unlikely to be prosecuted under the state's hate crimes statute since the notes were not directed at a particular person.

Ron Meier, New York Regional Director of the Anti-Defamation League (ADL), said similar messages were previously discovered in Manhattan, Westchester and on Long Island.

"ADL is working closely with local authorities investigating the incidents," said Meier in a statement. "Individuals are encouraged to contact the authorities should they find these papers, leaving them in place."

City Councilman Brad Lander, a Democrat who represents Park Slope, said he was not aware of any tensions in the area that could have triggered the hate messages.

"The world is a tense place right now, but there hasn't been any other act of vandalism," said Lander, who took office last month. He noted that during the holiday season, there were some complaints about a menorah placed by local Chabad Lubavitch activists in the window of a Park Slope Key Food supermarket that had previously featured only a Christmas tree.

"I don't think that's related," said Lander. "This is a community that prides itself on tolerance and diversity, and that is much more indicative of 99 percent of the people. Unfortunately, it only takes one person to amplify hatred."
