When random thugs come to your door to kidnap you and/or your family, you defend yourself, and your family. With any force available to you. ICE are acting like these thugs, often not even in uniform, they are brown coats.

You didn't necessarily know who it is or what there intentions are.

And rule NUMBER 1 of being taken, is NEVER ALLOW YOURSELF TO BE TAKEN TO A SECONDARY LOCATION. Anything they would be willing to do to you now, they would be willing to do 10x once you're in a place they feel safe.

Anyways, the concept being that if it's dangerous for brown coats to "do their job" and kidnap people, they're less inclined to. And citizens have a right to defend their rights and their liberties.
