I found the image on the left, taken by David Hurn of Magnum Photos, while looking through Magnum Photo's website.  I then saw a Safety Officer talking to a student.  Both pictures are similar in that it is a male officer on a bike speaking with a female who is sitting.  The lighting in both pictures is also similar in that it is coming from overhead, but at an angle, which illuminates part of the Officer but very little of the student.
