with our guest .  David is a criminologist and professor
at the John Jay College in New York, but his field work in troubled
neighborhoods has revolutionized law enforcement, and made cities safer.

And, with the economy tanking and retail especially taking a hit,
we'll find out how one neighborhood is working to bring small business
to its main street.  Yavocka Young of is our
guest.
