JimDandy, the study you linked to did not specify "in the home."
That changes parameters, don't you think?
The "in the home" study included suicides; at the very least, it has been reported to have done so by several nationally published writers, and I have never seen their claims refuted.
Edit: Out of curiousity, I just checked Appendix 2, Definitions to the study you linked. Much to my surprise, Homicide and Suicide were not among the defined terms....
