Police Practices

Police officers have a unique role and position within our society. They have the vital and difficult job of protecting public safety, but they also must perform their duty without sacrificing civil liberties. The ACLU of Maryland works to ensure that police officers do their jobs without violating individuals’ constitutional rights.  We work  to promote police accountability and oversight, while educating Marylanders about their rights in police encounters.
