The Chicago Police Department is investigating the level of force used in an incident where an officer subdued an 82-year-old woman with a Taser. The woman, Lillian Fletcher, was reported to be wildly swinging a hammer when officers arrived on the scene. Worried that Fletcher might harm them or harm herself, the officers took her down with 50,000 volts of electricity. Fletcher, whose schizophrenia may have contributed to her actions, was rushed to the hospital but has since been released.
