Final answer:
Cannupa Hanska Luger responded to the Dakota Access Pipeline controversy by creating mirror shields as both protective gear and symbolic art for the protesters, which reflected the actions of law enforcement and workers.
Step-by-step explanation:
In response to the Dakota Access Pipeline controversy, Cannupa Hanska Luger, an artist of Mandan, Hidatsa, Arikara, Lakota, Austrian, and Norwegian descent, created a powerful art installation to bring attention to this issue. Luger created mirror shields for protesters to use, which not only served as protection but also symbolically reflected the actions of the law enforcement and pipeline workers back at them. These shields became both a means of peaceful protest and a profound art piece that transcended the traditional boundaries of protest art, spreading awareness and fostering solidarity among the pipeline opposition.
