You cannot compare the free stuff with cp. And yes, you can´t get arrested because there is simply no right to monitor you.
But if the Mall would be like the Internet, there was a cop store, indeed.
And there would be free shops where you´ll get everything for free. It´s not allowed but there is no police and everything.
Yes you can violate any law and you might even get away with it but eventually you will be caught. To think that someone has to police you and what you do is just crazy. Do you not steal or kill because a policeman is watching you?
Just because you can do something does not make it right or legal.
Check the language in your agreement with your internet service provider, most if not all do state that if you break the law they can block your access to the Internet. Your isp is not usually monitoring you the companies that own the copyrighted material usually monitor sites that allow people to download their stuff free. They in turn notify the isp. The Internet is under the rules of the country in which your isp is located. So yes there is a government police station. Learn something about the Internet and the laws that govern it. There was a big fight over the removal of a law in the U.S. Not that long ago. There was a law passed in Europe not that long ago concerning cookies. There have been numerous file sharing sites that have either been taken down because of breaking copyright laws or have since stopping sharing files that are copyrighted.
So your argument is just so much wind trying to justify breaking the law.
1- If they have a filter installed that just tracks but not blocks you, the questioned source is de facto granted.
2- There is no police. There are only catchwords and access is limited. Look after the recent Lügde case in Germany. They only get busted by their stupidity.
3- There was a crackdown on filesharing sites and some closed but that is long ago and there are various such file hosters and there is everything for free or as torrent. There´s a well known "public enemy", a Chinese running the mega cloud, that was created by the same guy who ran megaupload, that the US concentrated on, for example.
