A house goes up in flames and somebody has seen someone running away with a can. The "witness" has no actual proof that the other person was near the house, caused the fire, or had anything flammable in the can. I guess you can call the "witness's" story conjecture, but somebody else is going to have to put some actual legwork into deciding if the fire was arson or just circumstances and unrelated. If a DA has enough confidence in the witness, some evidence of possible arson, and enough from the witness to pick a suspect, the case goes to court. The DA rarely has proof; he has conjecture, and generally a lot of documentation saying "maybe". So why in the case of suspected vote fraud, are the accusers supposed to have solid proof when they have no access to ballots, machines, etc? Why can someone be a viable witness and cause a case go to court in so many other things, but that's never the same bar for alleged voting fraud?
