what the heck is going on?

I have to admit to feeling more than a little shaken today. It seem my normal safe life has been tilted today. In the wee hours of the morning we had a 3.o earthquake in the Midcities area (suburbs between Dallas and Fort Worth). Then this afternoon, the small town feel of my little suburb was shattered when two bank employees were shot during and attempted bank robbery! So my question is what the heck is going on. We don't have earthquakes in Texas. I want say they absolutely never happen, but good golly, the ground is supposed to stay still, and when did big city crime him my little hamlet?
I'm not naive enough to think that this is the safest little town in the world, and I know we have crime just like everyone else. But we don't normally have shootings in the middle of the day. In one of the busiest parts of town. We have things like burglaries, vandalism, convenient store and fast food robberies. We have drugs, a few gangs and domestic violence.
We just don't normally have mad men with guns running around shooting people.
All this together has rather rocked my little world. I guess it's not so little or safe anymore. :o(
They had to lock down the nearby schools to make sure the kids were all safe!
