BULLET TESTS OFF TARGET? For thirty years, the FBI has used a chemical "fingerprint" test to match bullets and the boxes of ammunition they came from. Hundreds of people have been jailed as a result of these tests. But now, the Los Angeles Times reports, "emerging scientific evidence has called the technique into question."One former FBI specialist said he had long been "concerned that the premises used to support the (bullet testing) practice seemed to contradict basic principles of metallurgy."Several people, previously convicted on the tests' strengths, are now moving to re-open their cases. Others accused of wrongdoing are now successfully challenging the tests in court.
