This question apparently will never go away. Here is my answer from July 2010 which still stands:
Dan O. said:
Only an idiot would choose to enter a potentially occupied cottage by way of the "exposed from all directions" balcony. When Rudy breaks the window and the occupant wakes and turns on the lights, where is Rudy going to hide on that balcony?
Isn't it something? A multiyear game of whack a mole.
A guilter named Kermit did a powerpoint some years ago on "the impossibility of the break-in through Filomena's window." I was neither here no there on guilt at the time, just thought of this as a fascinating "whodunit". The friend used to work at the local courthouse and knew such things....
Basically he said that whoever did that powerpoint was "overthinking" this. To his eye Filomena's window was an obvious point of entry, particularly for someone who knew what they were doing. (This was two years before the Channel 5 demonstration in 2013 which demonstrated in spades what he was talking about.)
On the issue of the deck at the back, he noted that being on a deck means unnecessary exposure, and I cannot remember if he knew about the streetlamp. Basically he said that no experienced burglar would use the deck because, as you point out, there's no place to go if discovered. From Filomena's window all one had to to was jump down into the deep shadow below....
He also said that even if it was easy to gain access through the deck, it was equally easy for Filomena's window... the way he put it was that why go for a 95% chance of success on the deck, when there's a 94% chance of success through F.'s window? The extra 1% is not worth the walk around the cottage.
Again, all this is predicated in assessing someone who knew their way around second-storey break-ins. My guy recommended heartily that whoever Kermit was, that Kermit keep his day-job because he knew nothing about break-ins.
So whether right or wrong, the people who seem to know the lay of the land for these things are all agreed... it's doable through Filomena's and arguably preferable for many reasons.
Enter Judge Massei. Even the convicting judge thought it was doable... he just argued that Rudy would not have gone up and down to Filomena's window
three times.....
..... and the Channel 5 guy demonstrated that a climber would only have to go up once to accomplish the tasks Massei thought was so complicated....
..... talk about elements of wrongful conviction! And this mole is still being whacked in Dec 2013. None of it is real justice for Meredith.
