Greensboro, NC -- Monday's crisis in the nation's capital had emergency responders springing into action amid all the chaos.
There are dozens and dozens of police forces working in DC. According to the Washington Peace Center, some of the biggest ones include Metro Police, Capitol Police, Transit Police, and Pentagon Police.
Somehow all these agencies know their role in emergency situations like Monday.
"Whoever's scene it is, whether it's the local agency or the university, they're the most familiar with their location, the people involved, what's going on. They are the best resource to have most of the information," said Deputy Chief Dwight Crotts with Greensboro Police.
WFMY News 2's Liz Crawford found that agencies all around the country use national models that plan for multi-agency response.
FEMA outlines national recommendations to give local agencies direction in commanding huge, multi-agency operations.
ICS stands for incident command system and NIMS stands for national incident management systems.
These national models outline how all levels of first responders, government, and even volunteers can work most efficiently during times of crisis. The flow of information is critical. The commander is the chief of police of the jurisdiction in which the crime scene falls in. They have liaisons who send requests for specific help and then agencies send in support.
"There's one person that's in charge and then there's lots of people that feed that information to them and making sure that everybody is plugged in. Information flow is what's really critical," added Crotts.
Greensboro police said a recent example of multi-agency response was in April when police responded to a suspected active shooter on A&T's campus. Several agencies were there but the campus chief was in charge of command.
