<human>: Provide a brief overview of the text.

I live in a college apartment complex. I don't have amazing nice scholarly neighbors. I live next to a couple that regularly fights. For a while it's been nothing but arguments. Which is fine. It doesn't bother me. 
But lately it's gotten a lot more aggressive. 

Some details to this couple are that they are both cheating on each other and they both hate that either one is unfaithful. They're both in their early 20s. They own a dog together. 

Last night my roommate informed me they got into a physical altercation. They broke their front door off. Their blinds are destroyed. And my roommate informed me the girlfriend even had the dog trying to attack the boyfriend. Both were very aggressive to each other. So there really isn't no "victim". When I went outside today I found my car side mirror almost broken off because they were fighting basically on my car. 

I want to leave a note or something telling them I will call the cops next time they do this. But I don't feel like it's my business. But at this point it's so bad and they're now endangering my property. What's the best way to let them know they need to knock it off so I don't have to get the police involved?
<bot>: I have aggressive neighbors that destroy property when they fight. I want them to stop but I don't want to call the police.
