When a law enforcement agency calls in whatever acronymed agencies they can (FBI, ATF, NSA, etc) in order to sway a case their way or appear to be more powerful than what they actually are.
Officer: We need to get this guy back into our custody.

Sergeant: Play alphabet soup! Call the FBI and the ATF to help us on this raid and get the NSA to spill his call records.
