Ms. O'Brien was on GMA to lend her support to bills being introduced into the Arizona House and Senate which would limit magazine capacity to 10. She is a sympathetic figure and you grieve for her loss. I think we can expect to see more of her as well as others related to this shooting being used to push for restrictions on standard capacity magazines.
Ms. O'Brien, however, gets it wrong when she says that it is "so sad to see 19 people gunned down in 15 seconds by one of these extended capacity clips." It was not the "clip" that killed her fiancee - it was a mentally disturbed person whose condition went unreported by school authorities and then ignored by the Pima County Sheriff's Department. It was Jared Loughner that killed Gabe Zimmerman and not the Glock 18 knock-off magazine. We can still grieve for Ms. O'Brien's lost love but we don't have to agree with her reasoning.
