I don't think that area is bad at all. And it's right by an awesome coffee shop I love!
I don't think that one stabbing should really dissuade you from moving somewhere. I hope that doesn't sound too callus...
Crime is so sporadic in this area, you could live in Bethany or the Pearl and still be a victim of crime. But overall it's VERY low, we were just rated #3 safest city.
