Haunted by what I've seen at the hardware store

I've made two trips to the hardware store in the past week and had to stand waiting to get a key made. At the "sporting goods" counter first time, 4-5 men buying guns. Second time (Friday), 8-10 men buying guns, notably handguns. I asked the guy making my key, "Is a season opening?" He said, "It's Obama's gun law." That's gotten me very worried.
