"she was frantic. . . she said he has a gun."
"when the homeowner came out of the room he had the gun in his hand."
"a police officer mistook the homeowner for the suspect and fired up to six shots, hitting him in the stomach and legs."
Ooops. Some will say that this is why homeowners shouldn't have guns in the first place, but getting the whole story shows that the victim stopped the criminal by using his gun, holding him at gunpoint until cops arrived.
