I think we all need to make hard copies of these 2nd Amendment sanctuary declarations to keep as a reference in case digital media goes down. Keep a file folder with hard copies of important documents.
Also, do not be afraid to have a discussion with your local Sheriff from time to time to see what they are thinking or have questions during debates before elections. I remember we invited the Sheriff to one of our group meetings years ago and asked good questions of what will his office do during certain crisis situations and if he needed a posse or something. We gathered afterwards he was a puppet and would follow his orders. But at least we knew that about him.
I even joked that if things got real bad, I would declare my property a sanctuary 2nd Amendment property among things and post a sign out front. Remember the Revolutionary era on how ordinary Colonists fired the first shots against the mighty tyrannical British that started the whole birth of our nation. We should not forget what ordinary Patriots will do under duress against such tyranny.
