Acorn is the Lest Wing’s version of the German Panzerfaust. It’s a use once but deadly weapon.
Even if the group is destroyed, they will have accomplished their goal of getting a Marxist elected President.
If law enforcement doesn’t bring ACORN under control, ACORN can take their tactics as far as they want. I suspect that sympathy for the far right back (along with a hatred of the far left) in Weimar Germany among the police and armed forces allowed the brownshirts and other groups to create anarchy unchecked. The authorities took sides back then. The authorities here don’t have to do that. They merely need to keep agitators from trespassing and breaking other laws.
