# How We Investigate

## 

## How does the FBI work a case?

It starts with world-class training provided to our agents, analysts, and other personnel at the FBI’s Training Academy in Quantico, Virginia. The FBI’s highly trained personnel then use intelligence, science, technology, and other tools to investigate federal crimes and terrorism. In some cases, the FBI turns to special tactics and teams to catch dangerous suspects in high-pressure situations. 

### Training

The FBI's world-class training program ensures our FBI agents, intelligence analysts, and other personnel are prepared to protect the American people.

### Tactics

Whether storming a barricaded building or getting into the mind of a killer, investigators use a variety of tactics to investigate FBI cases.

### Science and Technology

FBI investigators use cutting-edge science and technology in every investigation.

### Intelligence

As a member of the U.S. Intelligence Community, the FBI collects, uses, and shares intelligence to carry out its mission.
