What were the details of the stories that Rick told about the bodegas in New York City?

The bodegas were stores in New York City owned by men who came to America to find better lives. They work hard at their stores and saw them as freedom and respect. But the thieves were numerous. They robbed and killed. If only they had just taken the money and went things would have been better. They maimed and killed the owners of the bodegas who returned the next day to do it all over again because they had nowhere else to go.
