From now on, when D.C. government watchdog Dorothy Brizill wanders the halls of the John A. Wilson Building, she says she’ll be wired for sound or toting a video camera.

Brizill, co-founder of DCWatch and a thorn in the side of the city’s executive and legislative branches for the last 20 years, was arrested and charged Wednesday with misdemeanor simple assault following an argument with a District employee. The incident apparently started when Brizill entered the office of Deputy Mayor for Education Victor Reinoso searching for the phone number of Jackie Pinckney-Hackett, director of the Office of Community and Parent Involvement.
