Easy solution. Shoot one looter, and string him up from a light pole on your block with a placard around his neck saying “This is what we do to looters on this block”.
They’ll move to the next block, guaranteed.
And get life in prison or at the very least lose your life savings in lawyers' fees - especially if the looter is one of 0bama's sons. Look at George Zimmerman's reward for shooting saint Skittles. The police and the prosecutors will consider YOU the criminal. The police the only ones allowed to go around killing people without any consequences.
