In Heller, and McDonald, SCOTUS showed great wisdom in focusing equally on the firearms, and on the history and meaning of self defense. They rightly noted that there are reasonable restrictions on who may carry a firearm. These restrictions very closely match groups of people prone to use any weapon for felonious harm, and not for self-defense.
There's an old saying amongst self-defense advocates, when seconds count, the police are only minutes away. When seconds count, the employee's vehicle is equally distant. SB 411, while a step in the right direction, provides no additional means of self-defense for the employee. Further it might be argued in civil court that an employee might have some notion of liability in the event that there is an active shooter in the building, when the employee exits the building to retrieve a firearm, and then returns. Criminally speaking, a jury, or prosecutor could explore the question of a legitimate claim of fear for life/self-defense, as the employee was already safely out of the building, and chose to return to a building with an active shooter (willfully placing their life in jeopardy).
Our state laws place the burden of defending employees on the employer, and the employer responds by simply purchasing insurance to cover such an eventuality. Insurance does not stop bullets, and does not in any way defend the employee in the work place. The victims of a shooting (forcibly disarmed and helpless) will get a settlement if they survive, and if they don't, well they're just dead, never having had any sort of chance to defend themselves.
Our state constitution goes farther than the federal in this case. The people shall have a right to bear arms, for the defense of themselves and the State. This is an individual right, and explicitly recognizes no limitation on the right to keep arms for self-defense, not just in the home, but in day to day life. Our courts, and our legislature must recognize this right, and stop treating firearms owners, and those serious about their own defense incrementally less like criminals every day, and remove the unconstitutional restrictions imposed by employers on the carry of firearms.
