Wow. Those are a great sequence of photos. I had to use my DIY-CSI computer skills to open a new page copy and paste the link and password to get to the important data on that page for my own personal analysis. I also used my computer skills to figure out I can use the zoom feature on the individual high-res photos. The DIY-CSI photographer did a great job too. You can get a good sense of where the center of the bomb blast took place on the sidewalk about 1/3 of the way off the street and where people have been blown out of. Using that information, we can compare pictures and video from that exact location to find a photo of the person placing the bomb there.
"Fascinating" is a good reason for doing it.
