Stray dog under the house? Everyone is mad because I called the Cops.?

I went to visit my Mom in law and they have a crawl space that is open to the backyard. A dog got in there and wouldn't get out. My brother in law was spraying the dog in the face full force with a hose. I tried to tell him to stop. I even started pulling on him. I was about to punch my brother in law. He wouldn't listen. Finally, he said Fine and gave me overalls or something so I could crawl in. Which I did. The dog bit me. I kind of expected that. But after that he was nice and calm. I got him out and my brother in law started kicking him and I couldn't stop him so I called 911. I wanted him arrested for animal abuse. So the cops show up and I'm a dirty mess and hysterical. And the cops say well this is his house and if he doesn't want that dog in his crawl space then there is nothing we can do. The dog is fine. He's resting comfortably in our basement. We won't keep him. He'll find a nice home. We took him to the Vet and he's on a lot of meds. Worms and stuff. But now everyone is mad at me. Why did you have to call the cops? He wouldn't stop kicking the dog. Please tell me I was right for calling 911.
