The "doubt" is considerably lessened when there is a plethora of such evidence. I grant you that juries can better comprehend physical evidence, but when the amount of circumstantial evidence is overwhelming, the jury can convict w/out losing sleep....(The OJ jurors ignored both physical and circumstantial evidence and nullified the weight of both kinds.)

Exactly..

It's like money. Some evidence is "worth" substancially less than other evidence.

If it's worth less, then you need more of it.
