Reasons:
crime statistic bug in "Godwin" intro - enemy solider counted as civilian
kill count is accumulated through different saves loaded - I have a later save in same playline, and reloaded first save to test if Godwin killed "civilians", the statistic jump from 2 kills to 9 kills; i am quite sure Godwin did not kill 9 people in a single intro scene.
