That's the thing though...
your wife and/or daughter to be whisked away to Little St James never to be seen alive again
This only happens in movies. You seem to be imagining some kind of apocalyptic leftist purge.
At the moment your family is "detained" you quite simply do not know what the outcome is going to be. Are they just going to be interviewed, and released in an hour, or are they never going to be seen alive again. A violent confrontation, no matter the outcome, dramatically increases the likelihood of the latter.
Sometimes caring for people means considering their well-being before your own ego.
If you don't agree, god help anyone you ever "care for".
It's so weird.
