One of the more annoying things about the gun control debate is the phrase, "gun violence." The phrase is used by gun control advocates to imply that the problem is the gun, not the person doing the shooting. They might just as well call it "finger violence," since the finger to pull the trigger is needed just as much as the gun. Oddly, I have yet to hear anyone complain about "finger violence."
The displacement of responsibility onto something -- anything -- else is one of the favorite tactics of criminal defense. After all, if the gun did it -- or the brain lesion, or the botched Head Start program 30 years ago, or that one Twinkie too many -- then it would be unfair to send the defendant to the slammer.
Overlawyered has an example of an attempt, fortunately unsuccessful, to blame a barroom fight on what I guess should be called "beer bottle violence":
A Texas appeals court has affirmed the dismissal of a lawsuit seeking to hold Anheuser-Busch liable for an assault suffered by a bar patron. The suit alleged that the long-neck design of the bottle made it too attractive for assailants seeking a weapon; the court agreed with the brewer that the plaintiff had failed to make out a sufficient case to avoid summary judgment.
You really do have to be creative to think of this stuff.
