Granted, East Liberty (aka 'Sliberty) isn't necessarily the safest neighborhood to take a stroll in, but I can name at least five neighborhoods which are worse. I believe if you go looking for trouble, then you're going to find it. So if you want to find bad, criminals and what not, then I'm sure you can find one or two here.
A lot of businesses and stores have moved in recently, which I'm sure is not going to "rejuvenate" the area. I'm afraid that this so-called refuvenation is just going to push the poor people and crime to neighboring areas.
I can't say how long that I'm going to be in East Liberty and bear witness to the changes that it's going through. More and more businesses are cropping up in the main drag and surrounding areas. God knows what this neighborhood is going to be like five years from now.
