The Introduction of Tasers and Police Use of Firearms: Evidence from the Chicago Police Department
Keyword(s):
Many police jurisdictions have recently expanded their Taser arsenals with a goal of reducing officer-involved shootings. We analyze substitution between Tasers and firearms by means of an event study made possible by a policy change at the Chicago Police Department. Before March 2010, only sergeants and field training officers had access to Tasers; after that date, they were made available to patrol officers. We find that the change in Taser policy led to a large increase in Taser use, but not to a decrease in the use of firearms.
