Well in their defense, the FBI apparently only has five employees.
Seriously, this is the second time they’ve been responding to a scene where they expect there to be a major terrorist. And the only people that go to the scene are the three agents in this series and Jane Doe.
They’re looking for a guy who’s bringing a bomb to the Statue of Liberty. They’d have boatloads of cops being sent in to find the guy.
Same thing this week when they had a guy who was planning on launching a terrorist attack. They had him down to two possible addresses in Brooklyn. And the same four people - one of whom is a civilian - respond.
Here’s a thought: Call 911. The NYPD has a whole bunch of police officers already working in Brooklyn. They’ll get to the scene faster and with more people and have the guy already in custody by the time you arrive.
