I wouldn't want to make martyrs out of them, which is what that would do.

Instead, have a significant law enforcement presence on standby, and if things go that way, call them in, and round up every single one of them, in the moment, and put them all in jail, pending prosecution.

Speedy trial, sure, but another event like that will easily take months for investigators to sort out all the details and build the state's case against them. Meanwhile, they're all sitting in cells, losing their jobs, falling behind on rent and payments, having things repossessed, bringing shame and embarrassment to their families, and just so the state can't be accused of any sneaky legal maneuvers, their names and faces are to be plastered all over the media.

And bring reasonable charges, no plea deals or consideration of good behavior or lack of prior issues. When these people come out the other end of their sentences (years from now) make sure they have a nice felony conviction dogging any attempts to get their lives back on track for the next decade or three.

Make their actions and the consequences truly hurt. For them and their families. Make the spouses and children feel the pain, create resentment toward their flawed ideology that will last for a generation. And again, make it public. If these idiots want to overthrow our government, they don't get to slink back into the shadows of whatever armpit they crawled out of for the next 4 years. Let the media hound them, cameras in the street in front of the house, investigative reporters digging up embarrassing details of how they lost their jobs, the whole nine yards. Make their lives suck bad enough that the neighbor's wife starts telling her husband, "You can be pro-Trump all you like, but so help me, if you bring that shit storm to our family, I will divorce you and take the kids somewhere safe so fast your head will spin!"

In short, don't make martyrs out of them, make examples out of them.
