Well, I think this could still work. As to the group with signs, the only thing I could see possibly being against the law would be some type of "demonstration without a permit" violation. Someone could check in and get a permit and fix that. I don't see how you'd be denied such a permit, nor do I see how they'd clear you out if you had a permit as long as you weren't being belligerent or blocking traffic in/out of the building. As to posting the parking lot, that wouldn't fix their problem as you'd still be allowed to come demonstrate (although it would require disarming). And if we're not going there anyway, who cares if they post the parking lot? I don't really have plans to go park at the AMC Theatre and hang out in my car in the parking lot armed, just because.
As to the stickers, the post of the law on defacing of property supports this approach very well. It requires that a) you not place the sticker where it obscures the 30.06 (I wouldn't as that takes away from the effect) and b) that the sticker is easily removable, which I'm okay with. If you follow those two rules, I think you'd be okay. Put the sticker there and it lasts for a few hours or a few days until the owner or someone removes it, and some people see it and maybe even... think! (gasp!) And heck, it might even cause the owner/rep to think about it. Lather, rinse, repeat a few hundred thousand times and who knows what happens.
Anyone wanna crank out some (easily-removable) stickers and sell them here?
