Acording to the report I read, he broke away from the officers who were with him, ran into an adjoining office, dived through the glass and was killed when he struck a concrete canopy six stories down.
This does not sound to me like he was left alone near an open window.I could be wrong of course as I have not re-read the article today and my memory could be fuzzy
I'm prepared to take the story at face value but I realize that some of us always seem to want to put the worst possible face on some things, especially where law enforcment is concerned.
