answer:If I wanted to take over the US via martial law, I’d set up a denunciation system like they had in Medieval Florence. Very similar to what we had during the red scare, but more widespread. I’d get the churches in on it, too. Christians love being told what to do, and love nothing more than finding flaws in other people. So, set up a system where people can tattle on their neighbors for “un-American activity”, and have the denounced people shipped off to prison camps. You will be able to use the number of people in the camps as an excuse for increasing military presence in the area. People who operate in fear don’t use logic. It would work. After a while, the only people left would be the sheep that like being told what to do, and you can do as you like with them. Bear in mind this violates all sorts of Constitutional laws, but anyone setting up nationwide martial law probably doesn’t care about that.
