AMMUNITION/PROJECTILE PERFORMANCE CHARACTERISTICS (ACCURACY, FLIGHT ORIENTATION, IMPACT POSITION, VARIANCE IN WEIGHTS AND VELOCITIES) WERE TESTED AND A MEDICAL EVALUATION OF THE RESULTS OF TESTS ON BABOONS AND SWINE WAS MADE. TWO SCENARIOS WERE CHOSEN FOR EVALUATION THE SUSPECT FLEEING ON FOOT AND THE DISPERSAL OF A CROWD. MEDICAL EVALUATIONS FROM THE ANIMAL TESTS INDICATED THAT STUN-BAG IMPACTS TEND TO CAUSE INTERNAL ORGAN DAMAGES WITHOUT PROVIDING IMMEDIATE, FUNCTIONAL DISABILITY OR 'STOPPING POWER'. TEST SHOT DATA, WHEN APPLIED TO THE FLEEING SUSPECT SCENARIO, INDICATE A CONSIDERABLY HIGHER PROBABILITY OF UNDESIRABLE EFFECTS THAN OF DESIRABLE EFFECTS. IN SUMMARY, THE STUN-BAG APPEARS TO OFFER LITTLE TO LOCAL POLICE DEPARTMENTS AS AN AUGMENTATION TO THEIR PRESENT STANDARD WEAPON, THE .38 CALIBER. ANALYSIS OF THE TESTS SHOWED THAT THE STUN-BAG'S ABILITY TO AID THE POLICE IN APPREHENDING A FLEEING SUSPECT OR DISPERSING A CROWD IS MARGINAL AT BEST AND AT PRESENT DOES NOT ADEQUATELY SATISFY POLICE REQUIREMENTS.
