Why does someone deserve what you call 'due process' if one broke the law to come into this country?
Due process is a right reserved for citizens.
There, in all it’s glory, is your statement. It is not qualified by geography or anything else. You state, without qualification, that due process is for citizens only. Your statement is categorical and necessarily applies both within as well as without the US.
As such, it is false. Whatever the reach of due process outside the US, inside the US everyone is entitled to due process, whether citizen or not.
