i was just going to make a post about this. if trump decides you are an enemy of the state or a “threat to national security” and has you deported, citizenship or not, there’s nothing you can do to get home. he has full legal power to render you stateless.
Related, if trump is summarily deporting citizens under his new mass deportation regime, citizenship and an ability to appeal to the law isn’t going to get people back in the country. The executive runs border security
a) I think in practice this is likely true
b) I don't think this is because of Monday's decision. Monday's decision is that Trump can't be criminally prosecuted for wrongdoing. It's other, older decisions that have made it hard to get redress in other ways.
Formally, in the situation you describe, I think habeas corpus is still available to that person. Monday's decision shouldn't affect that. The problem is that the courts have gutted habeas protections and have made it clear that they don't care to rein in Trump.
To be clear, Monday's decision is appalling, a betrayal of the American constitutional order, and I think it makes it more likely that Trump will behave lawlessly because he knows he wouldn't be prosecuted.
