A secretive organization that can be found anywhere, anytime. It is a never ending mystery what ATAP stands for or what the organization actually does. But even so, they are here and they are watching. They know people too. Don't look for them, don't try to contact them, and especially don't question them. Don't mess with the ATAP, they will mess you up. Seriously...

Armando(ATAP member): Oh, so you are questioning me?! Yeah, you better shut your mouth before I punch your face in! MUTHAFUCKA! That's right Kefork-a-dork.

Dude, did you see that chick? ATAP man, ATAP!
