Why would you need to take precautions against it?
Against being a loudmouth, or against being rigid with some methodology? In either case I could miss the point, whatever it is, I'm sure.
The murder scene was part of the embedded processes that the Leprechaun included when he created the universe a few hours before the murder trial.
But what color are his shoes?
How do time distances make our conclusions any weaker?
We have enough difficulty mastering all the details associated with the span of a few short years in relation to an event that is local.
Now, I don't want to be postmodern or extremely agnostic/relativistic, but I don't want to just jump on the bandwagon about theories that involve such huge overwhelming spans of time/space, etc., either.
What about star formation in distant galaxies? What about dating a rock using radioactive decay? Is it appropriate then? If not, then why not?
Well scientists do their best and they have these conjectures. Ok. So question them, test them. Some conjectures are better founded than others, among scientific conjectures.
But some conjectures are more philosophical or more historical than scientific. Science may be applied somewhat sometimes, less so in others.
So if we admit that there are different types of conjectures, some better founded than others, seems more accurate than to go about talking about 'facts' of what happened many many thousands of years ago as if it were more than conjecture.
There's things that we observe, there's things we deduce. Among what we deduce, some of it is quite far removed from observed events or is heavily abstracted in some way -- there's a huge distance between the raw observations and the interpretation.
