>that gives thugs free rein to grab people who are not harming others off the street, and imprison them, is immoral,

What's harm? Do they have to have harmful intent, or would you object if their presence was unintentionally harmful? Does the harm have to be grievous bodily injury, or is economic harm enough? Why am I allowed to evict trespassers from my home even if they're causing me no physical injury, but the government isn't allowed to evict trespassers to our country unless they can prove some violent felony? It isn't some fundamental human right to live within the borders of the United States.

The issue is many are not trespassers. This is the equivalent of a guest in your house. They have paperwork and are working jobs, are legal residents and PhD students. The guest opposes a political policy you like. Instead of ending it in a reasonable fashion and showing them out sensibly, you call your son, a boxer and drug addict, to show up, handcuff them and take them somewhere. I never elected Rubio to decide on such things, and people that defend such decisions make me very uneasy.
