Thanks for the info. This shot is interesting. Why wouldn't JT use this safer route? Look how wide the path is?

She wouldn't use it for two reasons that I can se. There maybe more that I haven't thought of.
1) It was rather dark and kinda isolated along the alleyway at night. especially for a woman
2) The families wouldn't want to leave an unlocked patio door in that darkness. Possible burglars? Remember, the Mccanns patio was unique in that it was well lit from the street lamp
3) The detour for the front doors of the rest of the tapas wasn't so far as the Mccanns, and it was well lit by their front doors
4) The Mccanns had to make a much longer detour than the others for their front door. It was also hidden out of sight and in virtual blackness. No light for putting the key ion the lock and quite spooky.
Their patio door was well lit, in view and so close. No sookiness.
No comparison to the situation of the others.
