What would stop government agents from deporting me or you to an El Salvador prison? Are you ready to prove your citizenship at a moment's notice? Should we be required to carry our papers around at all times?

When the very question is whether someone has committed a crime, there has to be someone other than a government agent accusing you before the government can do something against you. Even if you believed that witches or terrorists or illegal aliens were subhuman and had no rights while non-witches or non-terrorists or non-aliens had rights there still must be a bootstrapping process (due process) to establish whether someone is in fact a witch or terrorist or illegal alien to avoid violating the rights of the non-witches or non-terrorists or non-aliens.

The only real rights are human rights: natural and negative rights. They do not apply to different classes of people. No one, not even citizens, have a "right" to health care, for example, they only have rights to not be prevented from voluntarily exchanging for health care, especially by a government.

So whatever that due process is, if the government has done it for that individual, they should deport. If they have not, they should not.
