what's the big deal with saying ... I'm a CCW permit holder and I'm packing. that's always worked fine for me.
question: say I'm shopping at homedepot or reasors, which hires off-duty LEO for security.
typically are near front door. if the LEO says hello as you pass... do you need to immediately inform LEO you are packing?
I think you only have to tell them if they are conducting official business with you. Like a traffic stop. Not if you are pumping gas next to one, or see one across the street walking the other direction.
