I have personally gone through that window - - it isn't so small. I believe Steve Thomas has gone through it too.
That bit about it being too small is BS.
John broke it so HE could get in when he was locked out - - and he isn't so tiny, either.
Other lies - - that someone couldn't step over the note on the stairs. I did it - - and I had someone take moving photos to prove it. It was not hard at all.
