A total of 127 of 188 randomly selected male police officers in a large west coast city returned the mail questionnaire, and 115 of 157 randomly selected firemen from the same city returned their questionnaires, while 82 of 113 questionnaires mailed to randomly selected male college students were returned. The police were found to be more favorable than either firemen or students toward eliminating procedural restrictions that hamper crime control effectiveness, even if eliminating such restrictions reduces the suspect's constitutional rights. Judging by the changes they advocate in procedural restrictions, it appears that the police believe that the present criminal justice system impedes the adequate control of crime; but in this particular sample, police crime control values do not generalize in the form of a distinctive antipathy toward judges. The police were not only the group most favorable toward 'the average judge' but were also the least cynical of the three groups about the fairness of the courts. Police are similar to the other groups in their beliefs that the risk of punishing the innocent is more serious than the risk of letting the guilty go free. Thus, while the police were unusually strong supporters of crime control values, they are also supportive of due process values while being unusually positive in their evaluations of judges and the courts.
