I guess it’s also not what he was actually charged with, but what he’s trying to do. It doesn’t take authorities much time to determine this.
So if he’s trying to plot a school massacre and was caught, and all they could get him for was some weapons charge, then maybe the authorities are hoping that he could be kept here so that he doesn’t go to some other country and actually do a massacre there. At least if he’s trying to do it here in Taiwan they could do something about it.
So yea he caused Taiwan to lose face because he wanted to commit a school massacre. All this nonsense about making firearms is just nonsense. It isn’t even against the law to make firearms in the US unless you are engaged in the business of it.
The indictment is likely to keep him from leaving Taiwan until they can figure out how to stop him.
