Mayor Rahm Emanuel says every Chicago police patrol car will be equipped with a Taser following a series of high-profile shootings by officers.
Emanuel says the city will double the number of Tasers available, to 1,400. Interim Police Superintendent John Escalante says 21% of Chicago officers are certified on using a Taser, but more training will be offered.
The mayor and Police Department have been heavily criticized since the city last month released video footage of a white officer shooting a black teenager 16 times in 2014.
Emanuel noted that on audio recordings of communications between dispatchers and officers on the scene that night, several officers are heard "frantically" asking for a Taser before officer Jason Van Dyke shot 17-year-old Laquan McDonald.
Police say no officers or vehicles on the scene were equipped with one.
