Yup, it was me, I got caught! By looking at the photos you'd be sure I stopped (see the brakelights?) but they actually had a video of it so I now know I didn't (unfortunately I wasn't able to download the video).
I always believed I stopped on right-turn-on-red stops - but apparently, in the early hours of a Saturday morning, I slowed down, checked for traffic and when I didn't see any, I started back up again. Yes, I'm a safe driver. No, I did not make a full and complete stop. Man was my face red when I saw the video (because with just the photos, I was swearing I did stop!).
You can bet I'm back to making sure I stop e.v.e.r.y time!!
