ETA: My understanding is that Guede had to make a "hazardous" (to whom?) climb to the second-story balcony. The climbs he undertook had many handholds and footholds, they were not hazardous to an athletic person. Maybe the out-of-shape police and prosecutor of Perugia would find such climbs hazardous; the exertion could cause a heart-attack in a vulnerable person.
Let's mention some of the pysical evidence of staging.
We find this set of elements, and we find them occuring all at the same time
(enumerated synthetically):
1. the window is an illogical point of entry (you can deny this, but you won't change this). Thieves just chose the easiest or safest way in;
2. there is no soil in Filomena's room (the soil below her window is dark and sticky);
3. there is no grass in Filomena's room;
4. drawers in Filomena's were not searched, they were completely untouched (usually, drawers are just the first place where burglars search).
5. No other room was searched by the alleged burglar; apprent focus only the "entry point room" has no bearing with reality;
6. the tossing of clothes from the wardrobe is something obviously theatrical and bogus, it's something nonsensical for a thief; that's no thief activity (drawers in all rooms would make sense).
7. no valuable item was taken (despite many were easilly transportable);
8. money in Knox's room was not taken;
9. Amanda Knox fell into serious contradictions on her "discovery" of the alleged burglary: she "forgot" to check for her cash, she allegedly went to check in her room because worried about her laptop, but she "forgot" she had already been in that room that same morning to undress, to dry herself and to change herself (and the laptop is the most visible object as you enter the room); in her Dec. 17. interrogation she contradicts even her own version once more;
10. the window shutters were left closed by Filomena, albeit not locked; which a) further complicates the illogical entry, requires to climb twice, and then, b) subsequently, the shutters were found half open (they would be open if the thief entrerd thought there; they would be closed if the thief wanted to shut them: it makes no sense for a thief to leave one shutter half open, only a forgetful stager could do that; and there was not enough wind, nor in the rigt direction);
11. the rock bowled on a paper bag ripping it, and the ripped paper below the rock has fallen on top of a cloth that allegedly would have been tossed there by the burglar. Many people appear to forget about this; but this is one element more that shows that the rock was thrown
after the clothes had been already tossed around.
12. the glass shards on the sill were not touched; any thief balancing there or holding there somehow would tend to remove them or anyway disturb them, move them, collect them or make them fall. Yet they are untouched, as if nobody stepped on the sill.
13. Filomena testified that items (such as the laptop, covered by a tossed cloth) were covered by tiny pieces of glass;
14. no DNA from epithelial cell found on the sill or on the window frame;
15. there is large crumbles of white paint from the painting of the window inner shutter that were fallen on te clothes strewn on the floor (further evidence suggesting clothes were tossed before the smashing);
16. no footprints were found on the soil/grass beneath
17. the rest of circumstantial evidence pointing in the direction of Knox being in the room carrying Meredith's blood, rather than Guede (mixed DNA vitcim + Knox in Filomena's room on luminol stains), no glass outside, the manouver of opening the window sticking an arm though a guillotine shaped glass while climbing a wall seems dangerous and not something a burglar is eager to do, testimonies of police about the soil being wet, lack of relation between burglary and the kind of murder (rape and extreme violence) etc.
