Korean law

It's kind of similar to the Miranda Rights.

The police can't beat a confession out of you. It happened to look like a beating... so they had to let go of the case.

Completely agree. Are Korean cops really this incompetent? They guy confessed to killing 12 people, and had details which were not available to the press. That alone should have been enough to detain him, it is not like they needed to find the bodies "within the next 12 hours". It was ridiculous.

Furthermore, the killer was covered in blood when they arrested him. So what do they do? They leave him all alone with a single female cop, not even handcuffed to anything. He can walk around the room, no one is there. Then when they cut him loose, the same female cop is the one tailing him (and she is hardly discrete about it). She follows him all the way to the store where he kills two people, and she doesn't even know! What exactly is she doing? Standing around outside the store for an hour doing what exactly? The cops all care more about the killer's rights than any victim he may have slaughtered. Oh, he has a swollen eye, better let him go even though he confessed to killing 12 people with intimate details.

The number of coincidences in the movie was ridiculous. The guy searching for the killer has a traffic accident with him. Convenient. Then the girl escapes, gets to a store, and guess which store the killer decides to get a pack of smokes from? And the shop-owner, knowing there is a psycho in the neighbourhood, proceeds to tell the psycho that she is hiding a girl in the back while waiting for the police. A guy with a smashed up face!

It was a grisly gritty movie, which could have been good, but which suffered from lazy writing.
