Chris Peterson, senior staff attorney for the ACLU of Nevada, at the organization’s office on Wednesday, May 5, 2021, in Las Vegas. Peterson was detained by Metropolitan police while serving as a legal observer during a protest for racial justice in summer 2020. Now, he’s working to change the system that allowed police to detain a large number of people at the protests who never faced charges. (Ellen Schmidt/Las Vegas Review-Journal) @ellenschmidttt
