Gun Control Is as Old as the Old West

5. It was basically illegal to transport a handgun in Texas prior to the Luby shooting Oct 16, 1991.

There was some arcane law about bonafide travelers, those crossing county lines, but basically that was considered unlikely by law enforcement officers. The unofficial way to transport a handgun was unloaded in the trunk with the ammo in a lock box in the car. This still wasn't legal but was overlooked. After the Luby's Cafeteria mass shooting that was the crack in the dam. One woman, Susan Hupp, had an gun in her car during the shooting where her parents were killed.

The Texas State Rifle Association and others preferred that the state allow its citizens to carry concealed weapons.[14] Democratic governor Ann Richards vetoed such bills, but in 1995 her Republican successor, George W. Bush, signed one into force.[16] The law had been campaigned for by Suzanna Hupp, who was present at the massacre; both of her parents were killed by Hennard. She later testified that she would have liked to have had her gun, but said, "it was a hundred feet away in my car" (she had feared that if she was caught carrying it she might lose her chiropractor's license).[15] She testified across the country in support of concealed handgun laws, and was elected to the Texas House of Representatives in 1996.[17]
