Criminologist: Increasing the current prison term for robbery will result in no significant effect in discouraging people from committing robbery. Each of the following, if true, supports the criminologist's claim EXCEPT: ['Most people committing robbery believe that they will not get caught.', 'Many people who rob are motivated primarily by thrill-seeking and risk-taking.', 'An increase in the prison term for embezzlement did not change the rate at which that crime was committed.', 'Prison terms for robbery have generally decreased in length recently.']
