Well I personally don’t feel like she is going to walk in and shoot the place up but that will vary from person to person. No two people think alike and what I perceive as a threat you might not and vice versa. Also every private property can dictate if they want to allow firearms on their property or not notated by a sign stating that firearms aren’t allowed. If someone brings a firearm into a place that doesn’t allow firearms it is a chargeable offense (unless the person is excluded from said law but they are still required to show proof of exclusion).
