That is the key to stopping confiscations. If you kill my family in an illegal act there would be retribution, a blood feud as it were. Leave me alone and I leave you alone. You kill my family members the law gets a chance to serve justice if they don’t and fail, it will be served one way or the other.
If two or three of these goon squads are killed to a man they will have a hard time getting personal for them. If the fight is taken to their families even more so. I pray this never happens, but freedom isn’t free.
That is an extremely big "If". It is certainly beyond the skills and capabilities of most firearms owners. And targeting their families will definitely harden the attitudes of police forces.
Competently managed police forces will not target the skilled 1% operators who might actually pose a threat of a counter attack. They will go after the "Elmer Fudd" and "Keyboard Commando" types.
There are plenty of authors and columnists who have gamed alternate resistance scenarios which probably have a much higher chance of success.
Specifically targeting "Celebrities", Journalists, Professors, "Public Relations Mangers" and "Community Activists" would be much easier and more likely to intimidate the Government without triggering an effective suppression effort. This is because Government officials hate some of their supporters almost as much as they hate their opponents.
"Divide and Conquer" works in multiple directions.
There are historical examples of this sort of thing with successful results. It clearly seems to work better than head-on attacks against police forces.
If you find yourself in a firefight with a SWAT team, then you are doing it wrong.
