It's true in Australia, true in the US, true broadly in the UK and Europe. Where do you live where it's not the case? I once got mugged, had the perpetrator's ID and a video recording of them doing it, and they got a slap on the wrist.

After being stalked myself, for years, across borders, I can tell you the police doesn't care unless you can prove real, imminent danger. I have no idea how to prove that short of a written confession. A message from the stalker with a picture of them holding a knife at the door of my building, and the text I came to "visit" you but you had guests/witnesses for example didn't reach the bar of imminent danger.

The police is made of people who want to do the job but are swamped with bigger problems, and people who don't want to do any real job.

Things are very different in the US. Police do not exist to uphold the law or protect civilians from anything. There are specific rulings in our legal code that flatly state police are not obligated to protect anyone.

Police in the US exist mainly to suck up tax money and harass and murder civilians and escalate peaceful protests into riots to justify suppression and murder. They're merely an instrument of an increasingly authoritarian government.

Yeah, if you gave police here a complaint with all the evidence in the world, there is absolutely no obligation for them to investigate or take any action. And there's really no recourse.

Be glad you live in a functional society.

Maybe you're being Naive? Just because there are laws doesn't mean there going to be enforced. Especially with what's going on right now with governments becomming authoritarian.
