Guys, it is not that an intruder is statistically likely to turn your gun on you, it's that suicide by gun has a very high percentage rate of effectiveness.
The majority survive gunfights. A very small minority survive a suicide attempt by gun.
Now, since hanging is the second most common form of suicide by American males, and poisoning is the most common form of suicide by American females, removing guns would probably not have much impact on actual suicide rates.
Until we get rope control, and barbiturate control, and razor blade control...
