Study objective: This case series describes the injury pattern of the polic
e bean bag, a new weapon adopted by US law enforcement agencies.
Methods: Retrospective chart review between 1996 and 2000 identified bean b
ag injuries. Autopsy data were gathered for 1 fatality. Circumstances of th
e shootings, toxicology results, and psychiatric diagnoses, if any, were re
corded.
Results: Thirty-nine men and 1 woman between the ages of 16 and 77 years we
re shot by officers of either the Los Angeles Police Department or the Los
Angeles Sheriffs Department. The fatality was caused by massive hemothorax
after thoracic penetration. The locations of serious penetrating injuries i
ncluded the thoracic cavity, eye, abdomen, arm, and leg. Blunt injuries inc
luded splenic rupture, pneumothorax, compartment syndrome, testicular fract
ure, subcapsular liver hematoma, and cardiac contusion. Complications inclu
ded hemothorax, pneumopericardium, wound infection, compartment syndrome, a
nd osteomyelitis. Psychiatric consultation was requested for 27 (69.2%) of
39 surviving patients. The Diagnostic and Statistical Manual of Mental Diso
rders, fourth edition (DSM-IV) Axis I was used for diagnosis in all 27 pati
ents. Psychosis was diagnosed in 16 (59.3%), suicidal ideation in 15 (55.6%
), and major depression in 6 (22.2%) of the 27 cases. Schizophrenia had pre
viously been diagnosed in 7 (25.9%) of the 27 cases. All but 1 of the patie
nts had toxicology screenings performed, and the results of 29 (74.4%) of 3
9 were positive. Of these 29 positive results, 15 (51.7%) were positive for
alcohol and 8 (27.6%) were positive for cocaine.
Conclusion: Awareness of the broad scope of potential injuries mandates a t
horough evaluation of both blunt and penetrating trauma in patients shot wi
th police bean bags. The scope of these injuries raises significant public
health considerations because use of this weapon has been adopted by law en
forcement agencies in all 50 states and at least 10 countries.
