Jeremy Sisto says New Yorkers don’t always have the patience for his show “FBI,” which films on the city’s streets“You have to wait 10 seconds, but 10 seconds is a long time for a New Yorker,” Sisto, 48, told The Post. “And it’s always the young [production assistants] who have to break the news” to wandering pedestrians.His nephew worked on the set of the show — part of a three-series CBS franchise which is airing its crossover episodes on April 4 — and once tried to stop a woman who didn’t heed the warning to halt while they were filming.“So he just sort of grazed her arm and was like, ‘Excuse me, ma’am.’ And she’s like, ‘You touched me!'” the actor recalled.
