I think you're reading into it what you wish to hear. Her brother gave her the piece. Whether she selected it or not is unknown. Further, it is unknown if she is one of these people who think a gun in the house is some kind of mystical talisman that will ward off bad guys - without any further training or psychological preparation. In short, we don't know anything more about her than any other of the millions of people (many of whom are anti-2A) who happen to have a gun in the house. Remember, Sen. Diane Feinstein has a concealed carry permit (which implies gun ownership).
At this point, she is a totally unknown quantity.
Not quite. Here's what she wrote years ago, from a post by Dave Kopel at the Volokh Conspiracy.
The New Republic's fine &c blog points to a 1992 article she wrote for the Texas Lawyer. In the article, she points to three infamous multiple homicides in Texas: the 1966 Texas Tower Shooting, in which a man climbed the clock tower at the University of Texas, and shot 14 people. (He was finally stopped when two policemen and a civilian rushed the building.) The second was the 1991 Killeen massacre, where a man entered a Luby's Cafeteria, and methodically slaughtered 23 unarmed people. (The incident played a major role in Texas rescinding its ban on carrying concealed handguns, and enacting a Shall Issue permit law.) The third incident in Miers' article had taken place recently; a man murdered two judges and two lawyers in a Fort Worth courthouse.
"How does a free society prevent" such crimes, she asked. She then explained:
The same liberties that ensure a free society make the innocent vulnerable to those who prevent rights and privileges and commit senseless and cruel acts. Those precious liberties include free speech, freedom to assemble, freedom of liberties, access to public places, the right to bear arms and freedom from constant surveillance. We are not willing to sacrifice these rights because of the acts of maniacs.
Miers, however, rejected the notion that "precious liberties", including "the right to bear arms," should be sacrificed in the name of crime prevention. Quite obviously, she was referring to the "right to bear arms" as an individual right.
