Anyone who has seen the Killeen shooting story involving Dr. Hupp should be carrying.
When I grew up in the hill country, it seemed like every pick up truck in the HS parking lot had a rifle on the rifle rack in the rear window, and most of them had pistols in the glove box. Nobody thought about it or worried about it. When Charles Whitson opened up from the UT Tower, dozens of rifles came out, I'm told. The Tower is almost impregnable a perch but those guys kept him occupied while the police snuck up the elevator and took care of it.
I have been an attorney and foreclosure trustee here in California for nearly 40 years now. Starting about 10 years ago, every once in awhile we would get a death threat, over a foreclosure. A fellow in the South American agricultural products import business called one day to say: "If you don't do something about that foreclosure, we have big problems, Senor!" The best one was, "If you don't stop that foreclosure, I'm going to come down there and cut off your [deleted] and stick it up your [deleted]." The FBI interpreted that as a death threat. The perp was a big time real estate con man, now in prison. So, being an old Boy Scout, I figured I ought to be prepared in case one of these goons turned out to be more than a bag of wind.
I'm one of the few (~2000 maybe) in the county to have a CCW, we call 'em here. It took a long time, letters of recommendation, a special class, only three pistols by make, model and serial number allowed, a number of interviews at the Sheriff's Office, background check, shooting qualification with all three pistols, and a good bit of money as well. Being a lawyer and business owner was the key to having "good cause" which is whatever the Sheriff says it is. The CCW carries a list of restrictions so onerous as to make it almost worthless. It is only for business purposes, so if a BG tries to kill me, I have to ask whether it is business or personal, I guess.
I'm looking forward to retiring back home soon. I've already applied for the Texas CHL, waiting only on the class and fingerprints to be done.
Luckily, I have enough willpower to control the driving ambition that rages within me.
