So, for example, if a witness sees Oswald in the “sniper’s nest” at 12:30 p.m., that is
direct
evidence Oswald was at the “sniper’s nest” at 12:30 p.m., evidence which does not require a direct intervening inference from which to draw a conclusion (though, as we are about to see, it does require one or more intervening inferences related to the
authentication
of that direct evidence).
On the other hand, if Oswald’s fingerprints were on the boxes in the “sniper’s nest”, that is
circumstantial
evidence he was at the “sniper’s nest” at 12:30 p.m, evidence which
does
require an intervening inference. We have to make the inductive leap that the fact that a fingerprint
was
placed on a box could somehow logically be linked to the
time
it was placed on the box.
There are problems with both these types of evidence. For example, the direct evidence could be problematic if the witness had
poor vision
, or had excellent vision but was
located too far away
to make a proper identification, or if in fact at the police lineup the witness first identified
someone else
as being in the “sniper’s nest” (or otherwise refused to make the identification), or if at the lineup Oswald had on a dirty T-shirt while the others in the lineup were in three-piece suits, or a witness provided an identification that would have been physically impossible given the geometric relationship of witness, witnessee, and surrounding reality in three-dimensional space (i.e. the witness reported a
standing
shooter when a very short opening in a window would only support a
sitting
shooter), or the witness had made
other
identifications that turned out later to be
erroneous
, or the witness was
bribed
, or was
threatened
, or was
unduly influenced
by the media, or was
induced
to make the claim by a group of detectives at the lineup, or had his testimony
misreported
.
Hmmmm . . . not as solid as we thought!! I guess now you know why a
proper
trial has a technique known as cross-examination, which allows the defense to probe these areas for any points of weakness.
Circumstantial evidence has its own problems. You will note that circumstantial evidence requires one or more intervening inferences: for example, to conclude that “Oswald’s fingerprints on the boxes were evidence that Oswald was located at the ‘sniper’s nest’ at 12:30 p.m.,” your intervening inference would have to be that the
only
time those fingerprints could have been put on the boxes by Oswald was if
in fact
he was located at the nest at 12:30 p.m.
However, since Oswald worked at the Depository on a day-to-day basis, he could have handled those boxes at a different time, and, additionally, we cannot be absolutely
certain
that those fingerprints were Oswald’s, we only
assume
that they were. For example, to believe that these fingerprints were Oswald’s, we would have to reject the hypotheses that the fingerprint analysis was incorrect, and/or that the fingerprints were planted on the boxes at a later time by either Dallas detectives or the FBI (and this evidence would be less likely to support the element if the fingerprints of others were
also
on the boxes, which could potentially implicate those others as either accomplices or “the” assassin himself).
