This should be a un-ignorable reminder of the value of due process. Better a guilty person go free than an innocent person sent to their long, slow, undignified death.
I agree with you.
Now explain how can we scale the due process to deport everyone that entered here illegally in a reasonable timeframe. 15-30 million hearings will take a century to be resolved.
The system is not designed for such massive load in mind.
If the idea is that we are deporting people that are here illegally, it shouldn't be controversial to require some degree of evidence and a brief examination of that evidence by someone not immediately connected to gathering it, and some kind of oversight structure.
