Thanks everybody for your replies! The apartment manager didn't give my actual name, but said that it was my apartment that complained. Since I'm the only one who lives here - that sort of limits the possibilities of who could have complained!
Since they haven't done anything or threatened me, I don't think they would actually do something. However, they haven't gotten evicted yet so maybe that would push their buttons.
I'm really hesitant to call the cops. Sometimes they go through 2-3 minutes of silence where I think they just stare at each other, and then start yelling again. Part of me is afraid that if I call the cops, they'll be done by the time the cops show up. Sometimes they'll argue for hours, while other times they'll just argue for 20 minutes (just enough to wake me up and cause insomnia for a few hours!).
Regardless, I think I will call the police next time since the courtesy patrol recommended I call the police too. I can just tell the police that they told me to call.
However, this is the first time that I've complained since that final warning. And since there is no manager on site, I have to wait until the intern manager shows up next Tuesday to talk to her. I would think that this complaint would be the one to evict them. Although the last manager told me that sometimes they just don't let them renew their leases when they run out! Which is dumb because then I'd have to put up with them until their lease ran out.
My mom suggested that I tell this apartment management that I want out of my lease, and then I contact the old management that still has apartment complexes in San Jose and tell them that they need to move me (all expenses paid!) to an apartment in their community and waive my deposit until it is released from the current management (20 days after I move). I did really like their community and the services that they offered, and I'm sure this was just a bad manager.
Thanks for all the advice you guys! I slept on my couch last night just in case they argued because I knew I would not have the patience to deal with it again.
