When you deport somebody, how exactly are you depriving them of life, liberty, or property?
You're wrong. Point blank, you're wrong. They do have the right of due process, both by natural law and as guaranteed by the Constitution of the United States.
> In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence.
Restricting freedom of movement is certainly contrary to many definitions of liberty.
Sigh. For the umpteenth time, the US Constitution does not stipulate that non-citizens are subhuman. The right of due process, as described in the 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."
Note that illegal immigrants are still people. The US Constitution does not define them ipso facto as subhuman.
