"SHOTLIST
SKY - No access UK, RTE, CNNi
November 6, 2007
1. Pull out of Raffaele Sollecito, Italian citizen (covered face with jacket) leaving the police station
2. Amanda Marie Knox, US citizen and girlfriend of Sollecito (face covered with hat) leaving the police station
3. Lumumba "Patrick" Diya, Congolese citizen leaving the police station
4. Police vehicles driving suspects away in the murder of British student Meredith Kercher"
Knox and Sollecito went to the station on their own, unlike Lumumba. When could they possibly have been taken to the station?
