More than 100 guns had been turned in by noon, quickly exhausting the supply of gift cards until Brown's, led by Philadelphia grocer Jeff Brown, provided additional gift cards. "There’s a difference between just asking people to turn in guns — and we did that last year – and offering them an incentive, and it shows that this works," said Bilal Qayyum, president of the Fathers Day Rally Committee. The Greenfield Foundation, a Philadelphia-based charitable organization run by Emily Clark, offered $10,000 in funding for the incentive program. Clark said gun violence should be considered "everyone's problem." City Councilmember Cindy Bass, who participated the event, said the program helped address two critical needs in the city.
