You are talking about Suzannah Hupp, who followed the then-current law in Texas which forbade her to carry a gun at all. Before the Luby's massacre, she had sometimes deliberately broken that law by having a gun in her purse. Shortly before her parents were murdered while the three of them ate lunch together, she had decided to stop breaking the law and to keep the gun in her car, where it was legal.
That's hardly an argument against purse carry. It is an argument against failing to carry a gun at all.
It's surprising how many of these threads about female specific carry methods are so often taken over by guys who have never tried to figure out how to carry on a female body, with female type clothing.
