Seems like it's not pleasant, and the author says in theory it could be as low of a bar as getting into a heated argument; but the author never discloses his actual charge, which I think is critical context. If he stabbed someone and got this treatment, it would be very different than if he had a loud but normal argument you might see in any big box store in the US. That he doesn't go on to protest why he got locked…
I dont think so. I think innocent until proven guilty is the right way to go. Because all the police know is that he is accused of stabbing someone. Whether he actually did it or not, a court of law will decide that while he is present to be tried. Until then You cant punish someone like this over an accusation. You can deny bail if the person might be dangerous, but you cant punish them
This is bullshit and the japanese should be ashamed of having such a system while being considered a part of the civilized world. If this was china people would be rightfully losing their mind
