PHILADELPHIA (CBS) – This year marks the 100th anniversary of the Anti-Defamation League (ADL). It was created to fight hatred around the world.

The ADL was created to fight hatred against Jews, but it has embraced all kinds of bigotry and its ranks are filled with Americans who believe in combating prejudice; people like Philadelphia’s top cop, Police Commissioner Charles Ramsey.

“I think we’ve all seen progress but at the same time, we’ve all seen hatred re-emerge and sometimes in different forms. But it re-emerges, and we have to be very vigilant and do everything we possibly can in order to nip it in the bud.”

For Nina Timani, fighting hatred became a personal mission when she was the victim of a hate crime. Timani, an Arab American, was assisted by the ADL in her battle. She says there is a need for people to come together.

“You have to understand. Hate is blind. And it unites people that normally would not be united. Because it is an evil thing and it is a destructive force; not just politically but socially, emotionally, economically, everything.”
