>Someone from the "China tribe" did something bad to the "US tribe", so now we're going to grab a random member of the "China tribe" and punish them for it, even if they're not the one responsible.

Isn't it more like someone from the leaders of the tribe did something so we are holding leadership of the tribe responsible, given the extent that private companies are really extensions of the government?

>But having the president order arbitrary punishment without proof of guilt

Plea deals means that most people never have their guilt proven, only that they are strong armed into confessing so that harsher punishment isn't given. This is already the norm in any country that practices plea deals.
