John,
Your comment would make a heartfelt eulogy at these women's funerals.
Karate, a kick to the groin and keys to the face are not the weapons women need; they need a gun.
Ask young strong aware college girls; they want concealed weapons on campus.
And besides murder how many rapes would happen if the rapist thought they had the risk of being shot by a device that summons the police unlike a damn whistle.
Please give your speech at the next victim recovery group that will be attended by women who are not too traumatized to leave their homes. P.S. Rapists like knives; their quiet.
