HOW TO READ SCIENTIFIC DATA • On the average, not a single person would be misclassified by the HGN test
HOW TO READ SCIENTIFIC DATA • On the average, not a single person would be misclassified by the HGN test • Nevertheless, 37% of the sober individuals were classified as intoxicated under perfect laboratory conditions
HOW TO READ SCIENTIFIC DATA • On the average, not a single person would be misclassified by the HGN test • Nevertheless, 37% of the sober individuals were classified as intoxicated under perfect laboratory conditions • In the field 83% of the sober individuals were classified as intoxicated
HOW TO READ SCIENTIFIC DATA • In this, the most important of all the validations, 37% of the sober individuals were classified as intoxicated
HOW TO READ SCIENTIFIC DATA • Finally, in the two sets of data from the latest (and presumably most definitive) study, Burns demonstrated that 79% of the HGN tests run on sober individuals under perfect laboratory conditions classified those individuals as being intoxicated
So, in conclusion, we can answer the question,“Are the SFSTs designed to fail?”
YES. They are designed to fail if you hold to the belief that the law’s great purpose is to protect the innocent.”
For your future consideration:If you think the SFSTs are a disgraceto society, you will be appalled at the charlatans and fakers who try to sell you their “Drug Recognition Experts.”
