I honestly find it horrifying that you think stripping a person of their freedom and dignity for ten years is a reasonable penalty for being “noisy” on a train.
I’d much rather be around the noisy-but-relatively-harmless person than someone with so little regard for their fellow man.
>for ten years
Or longer if they show they are unable to reform while in prison.
>penalty for being “noisy” on a train
That is ignoring the second order effects of the situation. This noise is holding back the flywheel of public transportation that could have economic benefits to millions of people. The penalty is for the enormous cost of holding the rest of society back. The person who has such little regard for their fellow man is the one who is letting the few ruin society for the many.
