These kinds of deaths are totally unnecessary.
Most of the cops I know are good folks, but they can’t be everywhere all the time. If you think that–when a bad guy shows up–all you have to do is call 911–you are badly mistaken. In such a case, the police will arrive just in time to determine the cause of your death.
Given that she lived in Florida, Rucker–provided her criminal record was clean–could easily have obtained a concealed carry license. She could have gone to any local gun store, and received instruction on how to use and maintain a firearm. Had she taken this route, she would probably be alive today.
Oh, and you can pretty much forget about those “restraining orders”; they are worth the paper they’re written on.
