Law & Order: Special Victims Unit, Season 17

Man:
Barba, you don't know me or who I am, but we know a lot about you. Things people would want to know.

Barba:
Is that a threat?

Man:
A threat? No. A threat would be, right here, right how, I push you down these steps, get your skull cracked open, bleeding to death.

Barba:
Really? In front of all these people? Maybe they wouldn't be able to save me, but they'd sure as hell catch you. Alright, amigito, tell you what - you wanna murder a DA right here, surrounded by all these cops and cameras? Spend the rest of your life in prison? Here. Here's my home address. You come by anytime you want.

[the man leaves]

Benson:
Hey. Everything all right?

Barba:
Not really. Someone just threatened to kill me.

Benson:
What?

Dodds:
Who was it?

Barba:
Just a face in the crowd. Tell the squad to watch their backs. This is just the beginning.
