TASER Study Presented at the National Alliance on Mental Illness
Annual Conference in Washington, D.C.
Review suggests 45.3 percent of TASER system uses were used where lethal force could
have been justified in law enforcement contacts with mentally ill persons
SCOTTSDALE, Ariz., July 7, 2006 -- TASER International, Inc. (NASDAQ: TASR) today
commended Jeffrey D. Ho, M.D. and his research team in the Department of Emergency
Medicine at Minnesota's Hennepin County Medical Center for their efforts in an ongoing study
to track and analyze data relating to the use of TASER® electronic control devices in law
enforcement contacts with mentally ill persons. Ho's findings were presented last Friday, June
30th, at the National Alliance on Mental Illness (NAMI) annual conference in Washington, D.C.
The study utilized TASER International's voluntarily reported law enforcement TASER system
use database maintained since 1999. There were a total of 10,608 reports of TASER electronic
control device use in the database over a 72-month period. Of the reported 2,452 reports of
TASER system use in mentally ill persons, 1,111 (45.3 percent) were in situations where lethal
force would have been justified according to the reporting officer or where the subject posed an
imminent lethal danger to himself.
Although this data is subject to reporting limitations, the study indicates that in a significant
number of law enforcement contacts with mentally ill persons, escalation of the contact to lethal
force or suicide was prevented by a TASER device. The study recommends further research to
understand the impact of TASER technology use in contacts with the mentally ill population.
“Dangerous situations arise in law enforcement encounters with mentally ill persons each and
every day and TASER technology has been shown time and again to prevent the escalation of
lethal force and to prevent further suspect or officer injury," said Rick Smith, TASER
International CEO. “We continue to encourage and support further research into this
technology.”
