A report by Reuters showing Tasers being used liberally, sometimes on mentally ill prisoners, in Ohio’s Franklin County jail has prompted local officials and politicians to demand an investigation into the prison’s use of the device.

According to the Reuters investigative piece, “Each incident violated the jail’s Taser policy, and each was cited in a class-action lawsuit the county settled that accused jail guards of “sadistic” and unconstitutional use of Tasers from 2008 to 2010, court records show.”
