DHS placed the order, because they have a ton of agencies and personnel. The FBI is in DOJ. Separate and distinct entities and chains of command until one gets to the very top (POTUS).

The "Miami" (it did not happen in Miami, but nearby) shootout is an interesting reference. First, because it is the most significant incident since Newhall in terms of lessons learned about tactics. FBI agents are not cops, so tactics related to vehicle stops and associated violent resistance were not a front burner issue for them. Second, because it was the incident that resulted in modern handgun ballistics research. Third, because those agents had to fight through a crummy tactical situation against serious and arguably better armed opponents - none of the agents had a rifle. It taught us a lot about the nature of fighting against dedicated offenders, a lesson that is vital to LE of all types, and foreign to the cop haters who infest certain forums on the web, one in particular coming to mind. I avoid that one like the plague, and wish that most of its vocal members would put their bandwidth into adult entertainment research and self-gratification so they don't spout so much drivel, and hopefully never breed.
