Criminal Minds, Season 2

J.J:
Hotch, it's federal.

Hotchner:
What?

J.J:
If we want this case, it's ours. It's federal. This letter came from across the river, from Kansas City, Missouri.

Hotchner:
Interstate communication.

J.J:
Puts it in federal jurisdiction.

Hotchner:
[to Captain Wright] Sir, this is now a federal case. I would like to retain Detective McGee as a consultant.

Capt. Wright:
Whoa, whoa. You're not opening any investigations in my jurisdiction.

Hotchner:
I don't wanna fight with you, even though this is a federal case. If we develop any information, I will come to you and your men will make the arrest.

Capt. Wright:
And why would you do that?

Hotchner:
Because that's how we operate.
