Lethal good or bad

Paul Helmke never gives up:

LARGE-CAPACITY GUN MAGAZINE BAN GAINS ARIZONA VICTIM'S SUPPORT: In the wake of a mass shooting January in Tucson, Ariz., Rep. Carolyn McCarthy (D-N.Y.) and Sen. Frank Lautenberg (D-N.J.) introduced legislation calling for a ban on large-capacity ammunition magazines.

Now, both lawmakers have gained a supporter directly tied to the events in Arizona.

Kelly O'Brien -- the fiancée of a congressional staffer killed in the Tucson shootings -- is slated to join Lautenberg, McCarthy and Brady Campaign to Prevent Gun Violence President Paul Helmke at a press conference today to endorse the magazine ban.

Won't work, naturally, for the same reasons we've gone over a million times on all these "reasonable" control proposals. Here's a score of reason.com articles on point. Only need to quote from one:

How much gun expertise do you need to recognize that a firearm cannot be designed to do nothing but "shoot and kill innocent people"? I mean, how exactly would that work? Some highly sophisticated artificial-intelligence component that can peer into people's souls? More generally, even someone who has never handled a gun or read anything on the subject that was not published by the Brady Campaign should be able to understand that an instrument of lethal force can be used for good or bad purposes, and that features improving its effectiveness for self-defense would also tend to improve its effectiveness for criminal violence.
