The question isn’t about whether the constitution restricts non-citizens, but about whether it protects them by preserving their rights. In fact I’m not sure the constitution restricts any entity other than the government. It’s laws that restrict people. And laws apply to everyone, assuming jurisdiction can be established, or extradition will be enforced. I can’t murder someone in Japan just because I’m a non-citizen there. But I could break US law by doing something not-illegal in Russia, and they probably wouldn’t extradite me.
