A major drawback with cryptozoology - and a lot of anomaly research in general - is that it has to rely to a large extent on eye witness testimony. Of course, we would like additional evidence: footprints, photos, films, hair and other DNA samples, and - the holy grail - a carcass. But, by and large, before anybody even looks for such evidence, somebody has to see something - and tell us about it.
Now, eye witness testimony puts people in jail, so it shouldn't be scoffed at. However, as anyone involved in criminal investigation knows, there are eye witnesses and eye witnesses. To put it bluntly, some people's powers of observation and recall are less than adequate. To illustrate, let me share two double witnesses sightings I investigated. Even when two people see the same thing, there still remains the problem of cross-fertilisation, especially if they have discussed the matter before being interviewed, as is usually the case. Certainly, it is always important to interview both separately. Just the same, the bottom line is that two pairs of eyes are better than one. So, with these reservations, let us proceed.
