I came upon the crime stats in the previous post by reading John Harvey's blog. I met John last year in Memphis He is a cop and a nerd and darn good at both endeavors. After 32 years with the Shelby Cnty Sheriff's Dept, he retired and then later went to work for the Memphis PD.
He has created Cyberwatch in Memphis, an excellent tool to provide citizens notification of crimes in their neighborhood. I believe he also created the outstanding warrants database for the Shelby County Sheriff's Dept. His blog is excellent and highlights the problem of repeat offenders.
