There are a few things we all need to keep in mind here about this. First police protection, like any other resource is scarce. There is only so much of it to be had.
Even if there was unlimited police protection what can they do before a crime is committed? The hands of the police are restrained quite a bit by fears over civil rights violations. So, even if the police were there they are often times prevented from getting involved until it is too late. I like to say their main purpose is to secure a crime scene, take statements, and apprehend suspects.
We are primarily responsible for our protection. What does this mean? Learn about self-defense, get a gun and learn how to use it. Make sure your state allows concealed carry if it does perhaps consider strongly applying for a concealed carry permit, if it doesn't urge your state to allow concealed carry.
Yes, you can not say concealed carry (or a gun in general) automatically guarantees ones safety, but what is a 130 lb woman to do when a 220 lb man intent on killing her going to do at 9:42pm? Wave a restraining order in his face?
