When I was in Sansome Street's ICE detention area, there were cameras everywhere. I remember walking down a corridor with a female ICE agent by ourselves. I jokingly asked her whether she was going to attack me. She pointed out to me that someone's watching us at all times.
In Yuba County Jail, I don't even have to be escorted when I go to visit or to medical. I just walk by myself.
Today, I go to medical for routine questioning. Every door is electronically controlled by a deputy. I walk into an elevator and the door closes. A camera is inside. I walk out of the elevator and a camera is pointing at me. A nurse with a walkie talkie waits for me by the door. After I sit down next to the nurse, I notice a camera pointed directly at my face.
The only place that doesn't have a camera is inside the cell. However, there's an intercom connected to the control booth. The deputy can listen in anytime he wants.
You never know who's watching you or listening in on your conversation.
