Charles Mauldin witnessed the Selma to Montgomery marches in 1965 as a 17-year-old activist, enduring tear gas deployed against voting rights demonstrators. Now 78, Mauldin observes federal enforcement operations targeting immigrant children with similar chemical weapons during the Trump administration's deportation campaign.

The comparison drawn in this ProPublica investigation highlights the historical continuity of law enforcement using tear gas against vulnerable populations. Mauldin's experience bridges two distinct eras of American civil rights struggle. During the Civil Rights Movement, federal and state authorities used tear gas and violence to suppress peaceful protesters advocating for voting rights under the Fifteenth Amendment. Today, immigration enforcement operations deploy identical tactics against migrant children during arrest and detention procedures.

The legal framework governing tear gas use differs between contexts. The Chemical Weapons Convention restricts riot control agents in warfare, but domestic law enforcement agencies retain broad authority to deploy tear gas during civil unrest or law enforcement operations. However, the use of chemical irritants against children raises constitutional questions under the Fourth Amendment's reasonableness standard and the Fifth Amendment's due process protections, particularly when applied during immigration enforcement rather than riot control.

Mauldin's witness testimony carries weight as both historical documentation and moral testimony. His perspective connects the suppression tactics of the 1960s voting rights era to contemporary immigration enforcement practices. The juxtaposition forces examination of whether law enforcement standards have evolved regarding protection of minors and peaceful populations.

Immigration enforcement agencies operate under significant discretion in detention and transport procedures. The Department of Homeland Security maintains protocols for handling apprehended migrants, including juveniles, but enforcement agencies have documented tear gas use during border operations and detention facility disturbances. Legal challenges to these practices typically proceed through administrative law and civil rights litigation.

Mauldin's dual experience raises fundamental questions about whether America's legal and law enforcement systems have
