Sometimes you get asked weird questions, here is one I hope someone
can give me some insight to (I suppose I could get called to testify
on this).
The county prosecutor's office called me with the following question.
A car is sitting on an asphalt roadway. Blood is found around and
UNDER a tire. But they don't think the car drove over the blood (no
tracks). Is normal asphalt porous enough for blood to seep under the
tire without moving the tire?
I'm thinking probably yes (asphalt starts out as separate particles
so capillary action between the grains could do the job), but is
there anyway to establish that for sure? How porous is asphalt?
