I have definitely reshaped my thinking. But I did it over a year ago when I bought a Taurus PT92. I'm close enough to St Louis to be aware of what can happen when mob mentality takes over.
I don't carry the Taurus. Not yet. But I have it incase social unrest comes to my neighborhood.
During the Michael Brown unrest I barely missed getting stranded on Highway 270 when a crowd of protesters/rioters where coming down the embankment, just prior to shutting down the expressway. I could see the crowd coming down the hillside as I drove past. I just made it out of there.
