No real reason to capture this conversation unless the mall does NOT have such a policy.
I think we can all bet that since many malls do... this one does too.
You can let them know that the gang bangers are going to enter the mall with concealed guns. They are not going to follow that policy andthe mall will never know about it.
So what is the point in the policy?
I can assure you that it is not because they are robbed or have so many accidental discharges.
They have customers the do not like guns and feel safe knowing that guns are prohibited and are "magically" removed from everyone that walks in the mall.
Those customers spend money and that is what is all comes down to.
