Intercorrelations among MMPI scores, behavioral rating scales, and paired comparisons for twelve radio patrolmen showed that one of the characteristics responsible for much variability in the data was time in service, or experience. Radio patrolmen tended to fall into two distinct groups having specific characteristics. An individual patrolman in either group might be rated a high quality policeman. As a group, the observed patrolmen have a normal MMPI profile. The policeman's psychological development is discussed in terms of his need to cope with several role conflicts and his relative lack of job mobility. Two important fantasies concerning himself as a community service agent and as a crime fighter are observed to play an important part in these conflicts. Success in conflict resolution depends on mastering the problems. Failure results from fending them off and viewing them as external demands which lead to further job problems.
