The study concludes, "Guns kept in homes are more likely to be involved in a fatal or nonfatal accidental shooting, criminal assault, or suicide attempt than to be used to injure or kill in self-defense." I think this is a erroneous conclusion because their reported methods: "reviewed the police, medical examiner, emergency medical service, emergency department, and hospital records of all fatal and nonfatal shootings in three U.S. cities: Memphis, Tennessee; Seattle, Washington; and Galveston, Texas" only takes into account the times that guns were discharged, and fails to take into account times when guns aren't discharged, but are used successfully in self-defense.
The conclusion should read, "when guns kept in private homes are DISCHARGED, they are more likely to be used in a fatal or nonfatal accidental shooting, criminal assault, or suicide attempt than to be used to injure or kill in self-defense." But even this statement is a bit misleading.
How are these 626 shootings that occurred, "in or around a residence" related to the concept of "guns kept in homes?" Were all the guns used in these 626 shooting the property of the homeowner? Were any of them brought in from the outside? What about random "drive-by" shootings that often occur in neighborhood? Upon further review of their methods, they state they: "reviewed the police, medical examiner, emergency medical service, emergency department, and hospital records of ALL fatal and nonfatal shootings in three U.S. cities." [emphasis added] I assume from there, they narrowed it down to shootings "in or around a residence." But again, we don't know how many of these were private lawful gun owners in their homes shooting someone -- either himself, another illegally, accidentally, or in justified self-defense. But, despite this, they make the blanket statement that "guns kept in homes" are significantly more dangerous. Also, as I mentioned above, we don't know how many times a violent crime was thwarted "in or around a residence" by the presence of a gun, but without it being discharged.
Perhaps they go into the necessary detail of each of these shootings in their study. But, in reading their published abstract, his doesn't sound very scientific to me, and seems that the researchers were biased by an anti-gun agenda.
