Kottke has all the great links. Julio Diaz got robbed at knife-point in the Bronx earlier this year. "As the teen began to walk away, Diaz told him, "Hey, wait a minute. You forgot something. If you're going to be robbing people for the rest of the night, you might as well take my coat to keep you warm." NPR StoryCorps recording here.
Update: I don't mean to brag, but Kathleen from StoryCorps found my blog and commented on this post! Cool? Very. Check out her comment and the National Day of Listening project. Yay!
