SAN DIEGO — Bill Brierley was planning on seeing the downtown city library for the first time, but when he got to the front door he was turned away by security because of his service dog.

Brierly recorded the incident with his cell phone. In the video, he is seen telling the librarian on duty that his dog, Chase, is a service dog. and he is trained in medical alert. But the librarian says, “It’s not enough. Call the police. Kick him out.”

Brierley was incensed.

“My dog is a service dog with papers, and because I didn’t want to give the librarian the details of my illness, he rejects me from the library in direct violation of the Americans with Disability Act.”

The librarian in charge declined to speak with Fox 5, but the city released this statement: “City management takes these sorts of alleged incidents very seriously and will be conducting a thorough review.”
