Having seen other threads about knitting in movies I thought I'd share this one I just found in a TV show.
Dead Like Me, Season 2, Episode 2
George, the girl in the middle of the trio, goes to the police station to report her that her bike was stolen. She sits down between the woman who is knitting and the guy who seems to have a real problem. She looks at the guy's shirt and says, "I think he was stabbed. Yup, assault with a deadly weapon ... knitting needles."
