The images are frightening. A car pulls into a driveway. Two women get out and walk to the door. They stand waiting for someone to answer. When no one does, they return to the car and two men get out. Hiding their faces from the camera they obviously know is there, they go to the door and one smashes it with his foot until it opens. They go in the house, and run out a few seconds later, empty handed. The car drives away. The camera keeps rolling for two minutes.
The video was posted on YouTube from an Orinda neighborhood. This is why it's a good idea for neighbors to watch out for any suspicious-looking activity.
