What challenges do police and other first responders face in mass violence situations, in general?

Prior to beginning work on this discussion forum, read Chapter 16 in your textbook. Next, analyze the following scenario:

A suspect enters a crowded shopping complex and detonates a small but powerful explosive device. Calls to 911 reveal a chaotic scene. There are several people injured, and there are concerns that the structure could collapse with many more individuals trapped inside. Several witnesses reported seeing the suspect escape the scene. The suspect’s sister told police she found a notebook with details of plans to set off explosives in at least two other public locations near the current crime scene.
