One day I went into a government building which had "the sign". Unarmed security guards made me sign in. They didn't check me for weapons and I wasn't carrying. I asked the little security guard lady about what would happen if somebody came in there shooting up the place. Who would protect all of us unarmed citizens? She calmly said "nobody's supposed to have no guns.... didn't you see the sign?".
About a year later, an upset husband went into another government building, which had "the sign", and shot his wife and two innocent bystanders that happened to be in there at the time. Of course nobody could protect themselves because of "the sign".
When will people ever learn?
