The problem is not that the neighborhood is sketchy, the problem is that someone is NOTING that the neighborhood is sketchy. How is a sketchy neighborhood going to become unsketchy if it is common knowledge that said neighborhood is, in fact, sketchy? The solution is simple. We need to invest tens of millions of tax payer dollars creating parks and after school programs. At which point with all the fervor of an 1800's snake oil salesman/faith healer we enthusiastically declare the neighborhood healed. All the factors which originally led to that neighborhood becoming sketchy in the first place will somehow become irrelevant and a pox on anyone who purposely avoids the sketchy neighborhood prior to its transformation as they are full of hate.
