The memorial is called Only Light, and it's inspired by something said by Dr. King: "Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that." The memorial is also inspired by Leonidas's work: she was an expert in the field of lighting.
In a statement from Town Hall, Executive Director Wier Harman says the memorial is intended "shine our light—metaphorically and literally—in commemoration of Ms. Leonidas' life... A light directed outward from our building also symbolizes our gaze, and our witness last Wednesday. It seems especially fitting since one of Ms. Leonidas' contributions to our community is the light she left behind, both literally, in her work, and in the many lives she touched.”
Town Hall is hosting a conversation about the recent spate of shootings in Seattle with Mayor Mike McGinn, council member Bruce Harrell, and others on June 18. They will "discuss issues of public safety, gun control, mental illness, gangs, community response, and especially how a city heals itself after such tragedies." More information about that is here.
