How about this analogy....if it makes sense.

I have a right to defend myself against a dog attacking me. You own a restaurant where by law, dogs are not permitted (except seeing eye dogs of course). I am a customer at your restaurant and sitting out on the streetside restaurant patio (on private property). A person with a dog walks by and the dog bites me. Does the .gov and restuarant have an inherent responsibility to protect me even though dogs are not permitted because if dogs were permitted, I would of had my dog with me and chances are, the other dog would not have bitten me because my dog would of stopped it.
