<human>: Can you provide a brief overview of the text?

Last night, I went to a friends house and a bunch of us were hanging out.  One of the guys brought a guy he sorta knew (we'll call him Jake) to join us, and he gave us all some free drugs.  Most of the people go out to a bar, and some of us stay.  Jake returns, and we find out via a cell phone call that there are some guys (we were told they were undercover cops) looking for him.  Jake leaves his drugs at the house and leaves.

About 20 minutes later, one of the guys leaves to go see if Jake is okay, and these guys end up following him to the door.  They demand to talk to the owner and see all of the guys' IDs and ask if Jake Lastname is there.  We say we know a guy named Jake but we don't know his last name, and that he already left.  The guys begin to get their IDs, but the owner of the apartment asks if they can talk outside, and the two men say no, the door has to stay open, and make sure to show us their badges very quickly, implying that they were police officers.  We say that they need a warrant to come in, and they tell us that they don't and that we're aiding and abetting a fugitive and are all gonna spend up to 12 years in jail.  

My friend (stupidly) puts his hand on one of the guys, since he's trying to force his way in, and the guy immediately starts going off on how he has now assaulted a federal officer and is in deep shit.  Another one of the guys says that we don't know where the guy is and wants to know what they want from us, and the guy says that he's clearly drunk and could be arrested too... even though we're in a private residence.  He says that he doesn't want trouble with the police, and the guy says **"We're not cops."**  This entire time, they have been implying that they're cops.  Turns out they're bounty hunters.

Eventually they call the police, and the police search the place (with a warrant), and arrest one of the guys on a few year old MIP that he never paid for.
<bot>: While there are some things that were handled wrong on our end, do bounty hunters not need to say that they're bounty hunters and can they imply they're police officers?  And do they not really need a warrant?
