If I call the police on a neighbor, are the police allowed to let the neighbor know who called on them?

I called about an abandoned car in front of my house, been there for 2 weeks windows down. It has rained many days. I was worried about all the water and stuff sitting in it attracting bugs and who knows what else. I talked to neighbors and they told me they knew who car it was and that is all they would say to me. So 2 weeks of it sitting there I called the police and asked if there was an abandonment law. They never really answered the question, just stated they would come look at and talk to neighbors and tag the car so if not moved in 2 days they will tow it. Well they talked to neighbors, then came directly over to my home! Telling me they talked to neighbors and they claimed they told us that the key in it broke off and that they were gonna move it. I told the police, why couldn't they have called me to tell me this, that you are endangering my family coming over to my house to tell me this, in front of neighbors. The police was like smirking about (make me wonder if friends with the people, its a really small town) What if I was reporting something really serious? btw yes the neighbors knew who it was since they where standing outside when police came to my house. Is this legal? Thanks
