One other point for you and Frank to ponder. These were *not* high explosives. This could have been black powder, nitrocellulose, or match head pipe bombs. We don’t know. That information has not been released. But the Abuela was right next to the device when it blew and she lived. So it wasn’t gelignite, or plastic, or any of the other exotic instantaneous expanding compounds like those that were used in London.

Modern high explosives are laced with identification taggants that make tracing origin fairly easy for the FBI, so if they weren’t used that doesn’t really mean it’s not a trained expert. Expertise comes into play with the detonation circuitry, which reportedly was fairly sophisticated.
