How can any of those officers say her hands were perfectly clean though . They obviously were not .
Statements prepared for application to the CPS by police seem to be made to cover particular points. Her hands being clean must have been important to the case.
How clean were her hands? Well we can see blood staining to her wrist and a small stain on the back of her index finger, we can't see her palm or the insides of her fingers but Vanezis notes that they were free from blood staining.
If Vanezis is accurate, and we have no reason to doubt him, then on balance, a description of her hands being perfectly clean appears to be an accurate description.
