The shooting of the police detective has several issues. The abdominal wound shown would not have incapacitated him as shown. Unmarked vehicles unlike patrol vehicles do not have in-car video recorders. The corrupt detective would have been justified in firing as soon as Amy turned around, yet instead she kept talking, not firing until Amy ran away. Presuming the detective's wound was fatal, ballistics would match it to the corrupt detective's gun, not the one Amy was holding.
