All Jeremy can say about the kitchen window is -
I had no idea it could be locked from outside.
I knew it could be locked from outside but that does not mean I banged it shut from outside on the massacre night.
Either way he is highlighting an opportunity to fool the police.
He already admitted he could get into and out of WHF through the kitchen window when interviewed by the police. It is better he does not discuss this issue again in the 'Campaign for Freedom'. He hasn't.
