The Boyd case is still under investigation, but State's Attorney Scott Shellenberger determined that the officer who shot Gaines was legally justified in doing so. But that doesn't mean her death was inevitable. In a previous encounter with officers, Gaines had acted aggressively and erratically, and when police who came to her apartment to serve warrants found themselves in a stand-off, they were quickly warned that she suffered from mental illness. Her case was complicated because she was holding her 5-year-old son during the confrontation, but many legitimate questions remain about whether the situation could have been handled in a way that did not end in her death and his injury. "It really caused me to recognize that we need an outside set of eyes and ears ... to make sure officers are properly trained in these types of scenarios," Mr. Kamenetz said.
