Again, the assumption that "what you have been told" is correct, and if it differs from what comes out later it means the discrepancy is the fault of the ORIGINAL WITNESS and not the inevitable filtering of the rumor-mill sometimes euphemistically referred to as the media.
This is an example of what I'm talking about: Too many people, like you, are so wedded to their pet theories that they discard what is obvious in favor of their personal concoctions.
Please understand this (and it isn't the first time I've said it on these threads): WE DON'T KNOW THE REAL STORY OF WHAT WAS SAID AND WHAT WAS TESTIFIED BY MARY KATHERINE OR ANYONE ELSE!!!
All we know is what the Police allowed us to know. Misinformation is typically left to percolate, because it is better to have some details not generally known in order to aid the investigation.
I took Smart's comment about the knife, and about the window, to mean "now at last I can tell you the truth because the perp is caught!"
And the article in the Trib about Mary Katherine demonstrates beyond a doubt that she was THE most reliable of witnesses whose story never wavered.
