In Germany after WW1 when the Communist rabble were rioting in the streets of Berlin the returning German army put down the riots by the liberal use of live ammo in Spandau heavy machine guns & the use of “flamenwerfers”.
Also they organized technical auxillary corps of returning veterans & conservative citizens. Might be something to think about.
I’ll bet those “flamenwerfers” left a nasty scorch mark on the pavement. LOL.
