Elected officials, religious leaders and Adam Yauch's bandmate Adam "Ad-Rock" Horovitz gathered with a large crowd at Adam Yauch Park in Brooklyn today to denounce the swastikas drawn in the park this week and vow to stay vigilant against future hate incidents in New York City.

A crowd of a couple hundred people packed Adam Yauch Park, in order to hear a number of speakers condemn the swastikas and the increase in reports of hate crimes in New York City and around the country. "We have a bigger crowd than I think any of us could have imagined, which I think speaks to the strength of this community," State Senator Daniel Squadron told the crowd at the beginning of the rally.

Imam Khalid Latif, a university chaplain at NYU called the swastika a representation something that the rally goers had to remember: "Those individuals who perpetuated the most vile of acts against our Jewish brothers and sister in pursuit of genocidal mass extinction were only able to do so when those who had the ability to speak out against it chose not to." Latif told the crowd to not be bystanders to hate that happens in front of them.

"For us as New Yorkers, 'If you see something, say something' has to mean something different today. If you see hatred, say something. If you see racism, say something. If you see bigotry, say something," Latif said.

Rabbi Serge Lipp of the Broolyn Heights Synagogue brought up the case of Ivalyo Ivanov, the Brooklyn Heights resident who spray painted swastikas around the neighborhood and was eventually caught with a large home arsenal, as a warning to not dismiss the swastikas as "an isolated instance" of vandalism.

At one point, State Senator Squadron led the crowd in a singing of the national anthem, because as he put it, "this event is about American values."

"If hate is carried out in his name and he says nothing, it becomes his hate," Squadron said, referring to the "Go Trump" message that had been painted under the swastikas.

"I wish [Steve] Bannon could be here today, to see how he has brought us together. Our Muslim brothers and sisters standing with the Jewish community," Comptroller Scott Stringer told the crowd. "Our children, the next generation, with parents the way they never have been, to speak out and learn what unity means."

Adam "Ad-Rock" Horovitz addressed the crowd reading from a prepared statement. He correctly noted that "spray painting swastikas in a children's playgrounds is a messed up thing to do."

Horovitz linked the increase in hate crimes around the country directly to the Trump campaign, telling the crowd that they're happening "because we've elected a president that's given our children the message that it's okay to write 'white power' in their high school hallways. That it's okay to attack women and girls, that Latinos and Muslims and Jews are bad people, and that you can electroshock the gay out of someone."

Horovitz encouraged people to protest if they could, to give money to Black Lives Matter, Planned Parenthood and the United Way of Flint Michigan, and to volunteer. "Do what you can. Take what you're good at it and what your truly enjoy and lend your services to the causes you care most about."

Public Advocate Tish James called on the crowd to "organize, to mobilize and agitate the Hell out of this next administration," before telling some children near her "never to say that word."

Congresswoman Nydia Velazquez said that the crowd was "sending a strong message to those that would divide us" and called the vandalism a "result of the political climate of this past election." Velazquez called on Trump to condemn the rise in hate crimes in the country, and also blasted his appointment of Steve Bannon and Jeff Sessions to his administration. "When did you hear Donald Trump say 'Basta! Enough is enough!'?"

Acting Brooklyn District Attorney Eric Gonzalez announced that the Brooklyn D.A.'s office opened a hate crimes hotline—the number is (718) 250-4949—and said that "we will not stand for acts of bigotry in our backyard. We will prosecute those who commit these crimes."

Brooklyn Borough President Eric Adams, brought back memories of 9/11 to segue into how the city reacted on September 12th by getting back to work. "We do not allow the flames of hatred with planes to tear us down, I'll be damned if we allow an election to tear us down."

Councilmember Steve Levin called the vandalism "despicable" and decried the "rise of ethno-nationalism around the world." Levin called on Trump "to make it clear that anti-Semitism has no place in America in 2016. Swastikas have no place in America in 2016. Anti-Islam has no place in America in 2016. Fascism in America has no place in America in 2016. Naziism has no place in America in 2016. Neo-naziism has no place in America in 2016," and said that if Trump doesn't forcefully condemn acts of hate, he's condoning them.

The rally ended with the crowd singing "This Land Your Land:"

Before the rally, Squadron told Gothamist that there's no new information in the investigation of the vandalism, which remains under investigation by the NYPD's Hate Crimes Task Force.
