There is a mountain of evidence, and if each piece of evidence in that moutain is given it's own unique explanation, it can all be explained. However, it is important to view the evidence as a totality. If it can all be explained with one clear statement, such as "I was in another country at the time of the murder", then it works. That's not the case here. Instead, there are as many explanations as there are pieces of evidence, and that ultimately suggests that the explanations are more along the lines of excuses.
For example:
- Knox bloody footprints: not blood
- Sollecito's bloody print: reshape with photoshop and it belongs to Guede
- Knox shoe print on pillow case: fabric was folded only when Guede made that print, not folded for other pillow prints
- DNA on clasp: contamination in the cottage
- Meredith's DNA on knife: contamination in lab, or pricked with knife during imaginery dinner party
- Knox DNA on knife: she cooked for Sollecito, but they both said that he cooked for her
- Staged broken window: not staged, witnesses are confused
- Shifting alibi times: too stoned to remember
- Illogical behavior: the Amelie syndrome
- Failure to immediately contact police: police are confused
- Statement that Meredith routinely locked her bedroom: 6 witnesses misunderstood
- Phone call to mother before anything happened: doesn't remember making the call
- False accusation: police forced Knox to produce Patrick's name and blame him after approx. 1 hour of torture
- Confirmation of false accusations in two separate voluntary statements: unknown
[*]Failure to admit false accusation to authorities: unknown
- Lamp in Meredith's bedroom: Meredith put it there
- Sollecito DNA on Meredith's bra: Meredith shared underwear with Knox even though there was conflict between them
The list goes on ... and on and on.
