Businesses are free to ban law abiding citizens. So law abiding citizens are free to gather on public land near said businesses and hold informational pickets on just how unsafe those businesses are. Dangerous policy needs to be exposed. Turnabout is fair play IMHO. Now to find those willing to organize....that will put a stop to this "screw your safety, our irrational fears trump your right to self defense policies."
Food for thought... one hopes.
