In our local paper this morning is an article about a woman getting life in prison fro killing her husband with a .22 pistol. I just posted the link for verification.
Also remember that the little 4 year old girl that used her grandmothers .32 to put a bullet clean through herself. Last I hear she is doing fine.
Mouseguns can and do kill. I don't think anyone who says that they prefer a box of rocks to a mousegun is willing to back that up with being shot by one.
