At exactly 59 seconds the gunman, played by an actor, steps into a building, and the door closes. For a second or two we can see that there is a warning on the door about trespassing, and we see the word “handgun.” The full text of the statute cannot be read. If you watched the video (hopefully it will not be taken down), you see that the mock gunman had no qualms about entering the building armed. Though it was a scenario played out according to script and cast with actors, it followed what happens in real life quite well. Criminals have no problem breaking gun laws. The only thing gun laws cause is the law-abiding to be disarmed.
We are not a public facility.
