http://portugalresident.com/sites/default/files/040507_MR_FORENSIC_AT_MCCANN_APARTMENT%20(3)_2.jpg Chest-height or waist-height? After the alarm, anyone walking along there would be seen IMO.With your photograph, The photographer is standing fairly close in an elevated position so looking slightly down. The policeman is set right back so he would appear higher relative to the wall. Tis difficult to describe, but it gives a false impression..
Policemen are usually tall. Burglars are often weasely little blokes. This photo was taken from fairly close to the wall. Remember that the place was on a hill and the car park was elevated relative to the pathway and the closer one got to the wall the more one looked down on it.
The photo I show below is also taken from a slightly raised position but the PJ are close to the wall, which decreases somewhat the falseness. I think that on the path side, the wall would have been approx chest height for many burglars, especially if the viewer had been well back from the wall so the ground level differences made a lesser visual difference.

Getting closer as they approached would improve the situation in one way, but then they were looking in absolutely the wrong direction
Anyway, I personally do not think it likely that Madeleine went along that path, either carried or under her own steam. I think that she was passed over that wall with here head changing from the lifters right arm to the carriers left arm in the exchange.

See where the sill is relative to big man [ cop] PeterMacs waist and chest, then take in the difference of sill height to wall height.
I am inclined to think that even on him the wall would have been about chest height.
Do you agree ?
