I was told that title insurance companies use to write polices on tax sale properties but stopped around that time because of a few lawsuits.

In my state those are CRIMES, even if the police won't get involved you can still bring an action--and you should.Third--what are the occupancy laws in your community? 

As far as just accepting they won't pay, that is kind of like saying you left your door unlocked on your house and thief stole your belongings, so why bother reporting it to the police.

I had a different neighbor randomly call the police on my guests, complaining about noise in the middle of the day, while quiet hours are between 10 pm and 7 pm. 

I feel like saying - It is legal, but call the police if you like.

Can you simply ignore the complaining phone calls and police visits and the notices of city violation, etc that are part of the slumlord business.

People inside the home began to run off once the shooting happened and police started arriving.While no one was injured and no property damage was reported, several people at the scene were detained which ended in one arrest.

In the last year, over 250 police officers have resigned.

I would tell her to file a police report and let the police find it for her. 

Tell him to file a police report with the serial numbers of everything that was stolen.
