You are neither the only one, nor paranoid. I am not anonymous enough to be comfortable saying exactly how many I carry and where, but it is normal for me to have two SIG P229 pistols with me, and spare mags, on the clock or off.
I live very near where I work, though it is two different cities. I live in a statistically safe and quiet city, and work in a fairly high-end part of a big, busy city, to the north of where I live. Personal violence is rare, but when it happens, it HAPPENS. Very close to my home, in the small city, was a recent miniature version of the shootout scene from the movie "Heat," with just one bad guy and one police officer, and a police car turned to Swiss cheese. And the potential for more trouble is there, due to several items of what the DHS calls "critical infrastructure." Then, there is a major business center, in and near which are located several very high-end hotels and shopping centers, a Jewish cultural organization, an Israeli consulate, and a mosque. On the opposite side of where I live, is a major Jewish neighborhood, with several synagogues and other centers of Jewish activity. Through this area passes THE major land route between Mexico and the USA's Midwest, Northeast, East, and South. Can anyone see a potential for volatility? That is even before we consider the bad guys I have locked up over 25 years.
