If HE was your only source I imagine a few would be questionable.
The defense didn't rebut the relatives' trial testimony that the window could be locked from the outside. The family testified they were told this window could be locked from the outside and they tried it out and were able to get the latch to fall into the locked position from the outside. The latch moved up to unlock and down to lock so it will lock if it falls. Julie testified that Jeremy told her such window could be locked form the outside so established Jeremy was aware of it and planned to use it to get out.
They didn't have any expert examine the window and declare he tried to lock the window from the outside but was unable to ever do so and that it was not possible to do in his opinion. This suggests they were unable to find someone to test it who was willing to say it could not be locked from the outside.
The defense simply had Jeremy testify that to his knowledge the window could not be locked from the outside.
Who could be a more untrustworthy witness on this issue than Jeremy? Even on appeal the defense failed to come up with someone who would say it is impossible to get the latch to fall from the outside. It might be worth a little if they had someone assert such in the pardon application. They had no one who could say that though.
