I'm just stunned. A man walks into the coffee shop where 4 police officers are working on paperwork and turns around and shoots them. What stuns me the most is that this man was walking the streets. http://seattletimes.nwsource.com/html/localnews/2010385617_webmansought29.html Please keep in your thoughts the families of Sgt. Mark Renninger and Officers Ronald Owens, Tina Griswold and Greg Richards.
