Your point does not engage with the question raised in the comment you're replying to. Would you like to live in a society where criminal justice is secondary to immigration enforcement?

Dealing with the "root cause" does not require inflicting unnecessary cruelty upon other human beings.

Who is in power? What does our Constitution say? The executive branch is not granted absolute authority over immigration policy and the treatment of humans—citizens or otherwise. That is a Constitutional crisis.
