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.
What level of false positives are you willing to tolerate - US nationals wrongly deported?
How many fatalities (including suicides) are you willing to tolerate in this process?
(fairly easy to imagine hypothetical situation: lawful US national gun owner with Hispanic name is shopped to immigration by his neighbours. ICE come to his house in the middle of the night to deprive him of his rights. Is he (a) legally (b) morally entitled to open fire on them? If not, what do all the 2nd amendment tyranny resistors mean? If so, isn't this going to be a huge mess?)
