I consider myself fortunate. I run my own business from home and as the boss I set the rules. One of them is to be armed at all times.
Occasionally part of my job involves shipping items via USPS and I am required by law to not carry in the post office. I park in a nearby municipal parking lot, disarm and secure my firearm in a safe, while I conduct my business at the Post Office. As soon as I am finished and back in my vehicle I immediately re-arm.
Who are you and what do you think gives you the right to say I shouldn't be allowed to lawfully protect myself? Any law abiding citizen should be allowed to legally carry his or her own firearm in their vehicle.
