So what happens in reality is that once you draw the gun, you and your family are dead. By drawing a gun you doomed them.
If you value your family, you get out early. Pack up, move to a different country. It might be difficult, it might take a while, but if you start early enough you might just make it.
The Jews who moved out of Germany in 1933 could still sell of their homes and belongings, get a passport and visa comparatively easily and got out. The Jews who tried that in 1939 were in a much tougher spot and a staggering amount of them didn't make it any more.
So if you expect that there is a realistic chance that your family is sent to a concentration camp, get your family to safety instead of hanging around until it's too late and then get them and yourself killed. You don't become a hero for killing a few low-level grunts while dooming your family.
Ruby Ridge happened in a relatively free country. It was a huge misstep of a government agency and this went through the media.
If you kill some ICE people, then the telling will be that you are a crazy leftist terrorist who harboured illegal criminal rapists and that you then murdered some officers in a terrorist attack. The USA is not a free country any more.
Look at German newspaper reports from 1933 through 1939 to see what you can expect within the next months and years in the USA.
