I agree with you on the window not being a point of entry because of the things you mentioned. People, open to the truth, know it's one heckuva stretch to try and use that window as point of entry and exit. But, unfortunately, we have those, like Smit, who are hell bent on fingering an intruder. These are all too willing to believe Lou's theory and demonstration on how to get in and out the window. These will use that old scuff mark and suitcase as proof without considering all the facts. Then, you have those, like me, who was introduced to this case by Smit's crockumentary where he demonstrated how someone would get in to the window. If one had never taken a further look into the other side, one would be fooled by Smit's presentation. Fortunately for me, I began reading everything I could with an open mind. If someone could come forth with information which would put that window to rest once and for all, then, IDI are left with someone had a key. This really narrows the intruder list down.
