Right, but then who opened the window?
...and he enjoyed it that much & was that good at it he couldn't stop boasting to his mates about it, but then decided to just give up doing after that, even though he wanted to catch a little one & abuse it for days.
If CB knocked on the window and Madeleine opened the window, did he need to set foot inside 5A or could he just have lifted her out through the window after reaching in & raising the shutter? Are you using the open window as a defence now rather than part of proof of intrusion?
We have no idea how many children CB may have abused on his travels through Portugal, Spain, Italy, Romania, Switzerland etc. Without Madeleine's case, people would never have known about all the cases involving sexual predators on the Algarve in the noughties. It was reported that many of the children featured in the CSA images found on CB's devices were young & blonde, like Madeleine.
