I am have been renting a house for the last 6 months, the landlord has threatened to call the cops on me saying that I am breaking her house, she has called the cops on previous tenants, how can I get these reports

I doubt if you can. You generally have no right to know how many times the landlord has filed police reports on anyone but yourself. And you should know that by how many times the police have come by.

Your only concern should be whether the claims are false. If they are you may be able to file a harassment action. At that point you may be able to subpoena police records.

What are her specific complaints?

I think you might be able to find out how many police visits have been made to a specific address, which I think is public record. That wouldn't indicate who called, or what it was about, though.

Have the police been to question you about anything? What specifically is she accusing you of doing?

It sounds like you might want to plan to move instead of fighting this goofball. When your lease ends, get out of her world!

It will not help, if she called police there 100 times.

The only issue now? What is the issue, for the police call. If you are doing nothing, tell them to call.
