About 73 other people (besides LHO) worked in that building at that time. Not one of them said that they saw LHO at the time of the assassination. And, not one of them said that they were on the sixth floor at that time either. Is this just a coincidence or what?
Amidst your usual nonsense, Mr Collins, you inadvertently stumble upon an extremely important point.
Mr Bonnie Ray Williams testified that several of the guys had agreed beforehand to watch the P. Parade from the sixth floor. And yet not a single one of them ended up watching the P. Parade from the sixth floor. Every other in-use floor in the building had employees at windows, yet not the sixth--which offered the best view of all. What an amazing stroke of luck for evil Mr Oswald!
