I think it is disgraceful that the BPD never submitted the dna to any existing database for comparison to earlier or later sex crimes.

It is true that often databases have curation problems wherein the input data is improperly collected or simply rendered inadequate by later technological developments.

The NCIS is full of names of wanted suspects who all have the same physical features because the inexperienced operators who originally input the data kept hitting the return key to simply put in the default values for height, weight, etc. once they had entered the name of the suspect. So some care for data entry and data validation is appropriate.

I don't think the BPD is protecting any particular suspect, its just that once you start with 'The Parents Did It' and non-matching dna simpy has to be explained away or ignored or something. Sending the dna to a database would provide an identifiable suspect, no matter how remote the BPD thinks those chances are, they didn't want to do it simply because it would be the death knell to thier pet theory. Once the BPD became so wedded to their The Ramseys Are The Killas theory, contrary evidence would only annoy the BPD. DNA=Do Not Antagonize.

Given the absolute unwillingness of the BPD to have submitted dna results it makes one wonder whether these 'statments' or 'rumors' about suspects being excluded by dna results were based on any evidence at all.
