It's not necessarily about false reporting though. It seems to be about racially motivated calls.
A few years ago a cop relative of mine and a minority relative of mine were having a conversation about why minorities are harrassed constantly kinda no matter what they do. The interesting thing to come out of it was my cousin (the cop) said it's not so much that cops see a minority and can't wait to come bother them for nothing. It's that if they get a call they HAVE to go check it out. He said they get calls all the time even on the emergency line about "there's a black man walking through my neighborhood, he looks suspicious" and if you press these people on what's he doing that's so suspicious it's like "well he's walking around and he doesn't belong here". And the cops are still obligated to at least check it out.
Granted, that was probably 10-15 years ago, I don't know if anything has changed, and IDK it the cops are obligated by law, or policy, or for liability resons.
I'm all for stopping people from using the police to do their harrassment for them, but it has a huge potential to backfire.
BUT If I lived in a place with that law, I wouldn't call the cops about anything non life threatening or without some hard evidence. If I did call I'd be real hesitant to describe the person I saw. I'm sure as shit not going to assume anyones gender or describe hair, eyes, or skintone. You are one mistake away from ending up on the news for a hate crime.
