I think there is a lot of confusion about the climber's demonstration. I think it is important to clear this up, maybe even explain it to the judge and jurors.
Grinder is right that the guy does not get himself all the way up to the ledge without using the bars.
Bill and others are right that if you are not allowed to use the bars, then they restrict movement and hinder the climber's ability to climb up to and over the ledge. In fact, it is the reason the climber could not and did not do it.
But the climber was not trying to demonstrate he could climb up on to the ledge while the bars are in place. He was explaining and demonstrating how Rudy could have easily entered if the bars were not there.
Listen to what he says leading up to this:
01:19 'It is not a problem to open' (the shutters)
01:38 'And if you want you can break the glass and clean the pieces of the glass that remain in the window'
01:45 'And then you can pull yourself up and go in the windows without bars'
The above is when the climber pulls himself up to demonstrate how it would be done if the bars were not there. He is expecting the viewer to understand that if the bars are not there, and the window is open, it would be easy to complete the entry. He is expecting the viewer to visualize the rest!
01:51 'it is not difficult and enter in the house'
There is one other thing to mention. It would be even easier to just unlatch and open the window, rather than cleaning the glass from the inside of the frame. It demonstrates that the climber is not an experienced burglar.
