I read once about one city that did defeat WBC. It seems that while the WBCers were asleep in their hotel rooms with visions of protesting dancing in their heads, everyone in the city who had a van or RV or big trailer or panel truck brought it and parked it along the funeral procession route and in front of the cemetary. Some of the parking was illegal, but the police are under no obligation to ticket for a parking offense. The WBCers could protest all they wanted as long as they stayed on the sidewalk... behind the wall of trucks. Residents wanting to honor the procession could illegally loiter in the street to do so; illegal, but, again, the police are not obligated to cite for it. WBCers who tried to loiter in the street, on the other hand, were handled differently, but legally.
In another city, many residents dressed for the funeral in angel costumes complete with huge wings. They stood wing-tip-to-wing-tip along the route. Perfect!
In another city, a local funeral director provided a hearse and they orgainized a decoy funeral. The WBCers ended up protesting an empty coffin. Perfect!
