In a plea deal, he subsequently pleaded guilty to one charge. He was sentenced to 5 years, ultimately serving 34 months in federal prison.

#62: Ron Clarke

He led the UK Home Office Research and Planning Unit before going on to spend a long and storied academic career at Rutgers University in New Jersey.

Before moving to the US in 1984, Ron spent a decade and a half in British government’s criminological research department, the Home Office Research and Planning Unit, rising to position of Director in 1982. Clarke is best known for his development of the theory and application of situational crime prevention, although he also played a major part in the establishment of the British Crime Survey. He was among the first to realize that the secret to crime prevention wasn’t often-unrealistic broad societal changes but the careful and detailed analysis of the micro-environments associated with crime, followed with targeted interventions.
