But it is first necessary for you to answer the questions.<quoted text>
That's nice. So cut the BS and get to the point already.
1. Is looking for evidence that someone said something, the same as looking for evidence that a vehicle has passed a particular spot?
2. Do words have the same effects as tire tracks?
3. Do words leave impressions on the ground like tire tracks?
4. Do we not know that when looking for evidence of things, it is the nature of the thing that determines how that thing will/can be investigated?
