Follow the colored lines. The blue line (starts with the guy on the left in firefighter image), traces to his Twitter post, to DC ticket, to his license and other info, etc. I'm guessing the autists pulled those images off his Twitter. Same for the other guy, his trace is in yellow down through the right half of the collage. The 3rd person in the image they think is a female but they were unable to figure out who she is [yet], her trace is pink. Yes, you need a decent sized monitor to see all of the picture at once yet see the details, or ability to zoom in and navigate around the image. Essentially, the autists figured out who they were, found their Twitter, pulled key info and images off their feeds to provide most all the info you see. The cops pulling over the guy on the right baffles me, looks like a frame from a cop car cam when the guy got pulled over for something.
