DNA testing在1986年基本上还没有用到刑事侦查上吧?Google "DNA testing" or "DNA profiling", 你会发现WIKI上有这样一段话“In 1986, Richard Buckland was exonerated, despite having admitted to the rape and murder of a teenager near Leicester, the city where DNA profiling was first discovered. This was the first use of DNA finger printing in a criminal investigation.”
