Interesting read. It may just boil down to semantics. I think of "truth" as universal. Truth is intrinsic and does not require knowledge of it to be so. Facts can be used to argue for or against what is accepted as truth, but do not define what is true. Therefore, when someone speaks an untruth without knowingly using deception, it is still not truth. On the other hand, facts may be truthful in and of themselves, but that doesn't necessarily mean they will shed light on the larger truth. One example would be if a man is falsely accused of robbery. The facts may show that this man was in the visinity, fits the description of the culprit, fled from police when confronted, etc. All these facts lead to a false conclusion.
A lie is deception with the intent to deceive. So I totally agree that not all false statements are lies.
