The machine (red light camera, etc) is a recording instrument. The person is there to testify the instrument was set up correctly, properly calibrated, passed check tests, functioning normally, etc. Nothing weird about that.

Anyway, on first glance, the decision seems perfectly reasonable. Why shouldn't the party seeking to introduce a laboratory report into evidence be required to lay the appropriate evidentiary foundation by producing the laboratory technician to testify?
