The chief prosecutor in Baltimore City and Prince George’s County Maryland released their respective “Do Not Call Lists” after a Maryland appellate court ruling. The “Do Not Call Lists” are lists of former and current federal, state, and local law enforcement officers deemed unfit to testify by prosecutors because the prosecutors question the officer’s credibility. In some cases, the officers have been convicted of crimes. In other cases, the officers have been charged and convicted of administrative wrongdoing. In some cases, the officer has not been charged administratively or criminally. Serge Antonin and Clarke Ahlers evaluate “Do Not Call Lists” and offer support for their conflicting opinions.
