For a new start lets talk here. This meanders a bit but stay with me please. For several years in the past, the Dallas District Attornys have been getting 100% conviction rates. All of the sudden DNA testing begins to prove, in case after case, that the convicted and sentenced to death, are innocent. Even those who were convicted by eyewitnesses. They percieved the killer before them, but it just wasn't so.
I went to training one time where it was demonstrated to all present that three people seeing an event could easily give conflicting reports of the single event. In my time as a small town judge I observed this over and over again.
The point is that sometimes our perceptions, as real as they seem, can decieve us. Not that they always do, but they can.
I do not question anyones integrity, because what a person percieves is as real to them as anything can be. But I recognize that often we see and hear what we hope to see and hear. Nevertheless, I am a very strong believer that we do not know near as much as we think we do. In the future it may well be that we learn to measure things which we now cannot even prove exist.
