As things decline in the US, this is going to become more and more common and spread to much larger areas. The authorities are not coming to help but to try and keep the lid on. Obama has empowered these thugs and it is going to get much worse in the next three years.
Moving out of the ‘hood brings more problems for the criminals. They run the risk of armed retaliation. That’s why cities disarm their citizens. Mutually Assured Victimhood. Then people leave those cities and they collapse.
But the politicians in the collapsing cities will prop it up so they can rob it blind before the fall. If some black lady gets a bullet before the fall, what’s that mean to them? Big deal. Marching for Trayvon gets you on the news. Marching for TeQuila’s orphaned children does not.
