Here's a little quiz:
1-Do you sell drugs?
2-Are you in any way involved in organized crime?
3-Are you involved in an abusive relationship?
If the answer to all three of those questions is "no", then your odds of being murdered are pretty close to nil.
It's kind of funny though because I live in a significantly more crime-filled neighborhood than most gun owners, who tend to be paranoid suburbanites, and I'm not scared.
You can't take for granted one's need to feel safe though. I'm not a gun owner but if that's what someone needs to feel safe at home with their kids and belongings and what not then I can't tell them no, I can only tell them to be smart and act responsibly.
We're probably both on the same page on the gun issue though. I just don't like the idea of these Zimmerman types owning firearms.
