With the way various municipalities are bending over backwards to avoid offending the Occupiers, maybe the NRA, GOA, SAF, et al. should hold protests on that same model. Get together in parks, set up tents, dig fire pits, strap on their guns, sling their rifles, and hold up signs demanding our rights under the Constitution. Given that all sorts of city ordinances are being violated by the occupiers, and that the police have been told to ignore reports of rape, robbery, and drug dealing, they should also have to ignore people carrying guns as long as they have signs or T-shirts with political slogans.
And, the cities can't require fees or permits, since they have waived those for the Occupiers. And they should have to provide power, water, sanitation, and security, all for free.
