their children. today, eric holder put it like this. >> trayvon's death last spring caused me to sit down and have a conversation with my own 15-year-old son, like my dad did with me. this was a father-son tradition i hoped would not need to be handed down. but as a father who loves his son, and who is more knowing in the ways of the world, i had to do this to protect my boy. i am his father, and it is my responsibility, not to burden him with the baggage of eras long gone, but to make him aware of the world he must still confront. cnn contributor charles blow fred it another way. as heartbreaking as it is poignant, what pace should a young black man walk to avoid suspicion? charles blow is with us again. also, jeffrey canada.
