In 2005 I got a new digital camera, a vest pocket Casio, which would record night images unobtrusively without having to use a flash. To my mind, ordinary people, as they looked at that moment (not necessarily decisive) - just the mystery & wonder of there, then.
The movement or out of focus, is NOT deliberate. It's what the camera could do, not very perfectly. Wonderful camera. I still use it. The only faster capture of life I have known was my first Diana with a rubber band controlling the shutter.
