Police departments use complicated algorithms to predict where criminal activity will occur in the future. Future criminal justice managers have a potential role as change agents and need to recognize three distinctive patterns of change: straight-line change, rise-plateau-crash change, and cyclic change. In criminal justice, straight-line change patterns have involved training requirements, entry educational requirements, and in-service educational achievements, all rising gradually over the decades. The criminal justice manager must enforce the prohibitions, both in law and in ethical guidelines, against using public service for personal enrichment, profit, pleasure, or benefits not specifically authorized by law, the work contract, or the rules. Criminal justice managers with foresight will stay informed about new technologies and think of ways that they can be applied to criminal justice roles. When criminal justice managers were recruiting staff a century or more ago, a high school diploma was considered to be the symbol of an advanced education.
