History

Historical Context

The Posse Comitatus Act, enacted in 1878, restricts military involvement in domestic law enforcement, a response to civil rights abuses during Reconstruction. Recent events, including the detention of Army veteran Marcos Leao by U.S. Marines, challenge the application of this law, raising concerns about military authority on U.S. soil and its implications for future civil-military relations.
