Your own Constitution's Fifth and Fourteenth Amendments provide legal protection and due process for all persons facing criminal charges, whether US citizens or not. As per the text:
Fifth Amendment:
"No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, *WITHOUT DUE PROCESS OF LAW*; nor shall private property be taken for public use, without just compensation." [emphasis mine]

Fourteenth Amendment: also refers to *any person*, not just US citizens.

Even from Trump's party's own mouth:
"and shall employ *ALL LAWFUL MEANS* to ensure the *FAITHFUL EXECUTION* of the *IMMIGRATION LAWS OF THE UNITED STATES* against all inadmissible and removable aliens." [emphasis mine]

TL;DR: You can't just deport foreign criminals, regardless of their immigration status, without first applying due process, or you violate the US Constitution. If you honour the Second Amendment on the right to bear arms (which I am going to take the "liberty" to assume you do), you should arguably also honour the Fifth (and Fourteenth) Amendments on due process.
Disclaimer: not a lawyer or specialist in US law. But the Constitution is the Constitution.
