Here we have the plot of the main drama in an episode of Hill Street Blues being transformed into a significant scene in Aliens
a) Threats of gangs of become hoards of aliens
During the suddenly news that a proposed visit by President wont go ahead turns the gangs living in the Hill Street police station area become angered.
In the 43rd minute Lt Hunter is talking to Captain Furillo over the telephone to tell him that Lt Ray Calletano received a telephone call from a local gang threatening to send mercenaries to destroy the police station
This I think become the hoardes of aliens coming up the service tunnels to be shot en masse by the Robo-sentry guns

Later in his attempt to escape, he finds the urge to fix something else in the ceiling and before the 51st minute begins to fall through, being mistaken by the police for the gangs of villains coming through the ceiling.
The police have their guns aimed at the ceiling, with the expectations of the gang members crawing through. Before the minute is through, finally a hole opens up and Malibu falls down.
This becomes the hoardes of aliens crawling through the space in the cieling and crashing through it.

By the 38th minute, Rene Pegado, looking as if he wants to be mistaken for a little brother of Alice Cooper, is the head honcho of a gang is being arrested with other gang members,
He is yelling out with a blood curdling yellswho wont shut up about his claims that they are all going to die in the police station is transformed into Bill Paxton's Private Hudson who seems to have nothing better to say.
Before the 43rd minute, Detective Goldblume admits to Captain Furillo over the phone that he is nervous about having him around.
In the 45th minute, Pegado yells in the face of the police officer who is fingerprinting him, "Yo, pig face, gonna torch this pig house down tonight, Gonna open your ugly mouth and pour gasoline down your throat and light your tongue!"
He doesn't give up trying to create fear.
As the dropship explodes Hudson wails aloud "Well that's great, that's just fuckin' great man. Now what the fucj are we supposed to do? We're in some real pretty shit now man..."
Continuing moments later with the words "That's it man, game over man, game over! What the fuck are we gonna do now? What are we gonna do?"
Hudson hears the fact that it will be seventeen days before they can expect to be rescued after being declared overdue, and goes into another rant " Seventeen *days*? Hey man, I don't wanna rain on your parade, but we're not gonna last seventeen hours! Those things are gonna come in here just like they did before. And they're gonna come in here..."
He adds"...and they're gonna come in here AND THEY'RE GONNA GET US!"
Throughout the film he spews this kind of negativity forcing people to tell him to shut up.
Perhaps like Rene Pegado, he's there to tell everyone that they're going to hell and there's nothing they can do about it, making the other characters feel unstable
