..... would have been Keystone Cops. Directly across the street from the KKKers, preferably all men, costumed up like Charlie Chaplin: white shirt, black: shoes (old sneakers sprayed black), pants, tie, suspenders, mustache, and hat, oh yes... give them each a whistle (like those used by traffic cops). And tell them all to NOT utter a spoken word. They could only use their whistles. arms and legs to communicate. Oh yeah... they'd need a couple huge white signs that could be viewed from both directions with the word "BIGOTS" and arrow pointing to KKK group (in big black letters). The only other thing I could think of would be have a loud sound system with Charlie Chaplin music. By all means get any permit required well in advance of the event at town hall to counter protest. Call newspapers all over the state and tell them what you are going to do...a couple weeks in advance of the event. Don't worry about police...they will be there. Have several folks with cameras, in case the newspapers don't show up, then e-mail the .jpgs with attached article to all the media you can.
But hey, the folks that showed up in Charlotte were great! GO CHARLOTTE ! I looovvvvved that convention in Charlotte!
