CRIME ANALYSIS IS NOT A NEW CONCEPT, BUT ITS USE TO HELP POLICE ADMINISTRATORS MAKE MORE EFFECTIVE USE OF MANPOWER AND RESOURCES HAS ACCELERATED DURING THE PAST DECADE. BASICALLY, CRIME ANALYSIS IDENTIFIES EVOLVING OR EXISTING CRIME PATTERNS, PROVIDES THE PATROL COMMANDER WITH DATA FOR PATROL PLANNING AND DEPLOYMENT OF SPECIAL OPERATIONS UNITS, AND FURNISHES SUPPORT DATA FOR CRIME PREVENTION PROGRAMS. TO BE USEFUL, CRIME ANALYSIS MUST BE AN ESSENTIAL SUPPORT FUNCTION. CHARTS DESCRIBE TYPES OF CRIME DATA NEEDED FOR VARIOUS TACTICAL DECISIONS. VARIOUS WAYS IN WHICH THESE DECISIONS CAN AFFECT PATROL STRATEGIES ARE DISCUSSED IN DETAIL. USE OF SOLVABILITY FACTORS TO DEPLOY INVESTIGATION RESOURCES AND ANALYSIS OF CRIME DATA FOR CLUES TO FUTURE CRIMES ARE CONSIDERED. SAMPLES OF DAILY AND WEEKLY PATROL BULLETINS ARE INCLUDED. THE EXPANDED ROLE OF THE PATROL OFFICER IN CRIME PREVENTION AND INVESTIGATION IS DISCUSSED AND SUGGESTIONS ARE MADE FOR INCREASING OFFICER EFFECTIVENESS AT THE SCENE OF A CRIME.
