This is a tough one and I can see it both ways.
I think the key is that it’s anonymous. So that you can use this to harass people.
What if I anonymously called and said you had a bomb and illegal guns in your house? The police raid you and find nothing. Who is held responsible for this activity? The police were just following up on an anonymous tip. Hell the police could even call it in themselves anonymously...no warrant needed. Call in an anonymous tip that some child is being kept in the basement...no need for a warrant now. Ooops we didn’t find any kids but we did find something else.

Isn’t that the definition of “SWAT-ing someone”
