They (police) didn't come. The business owner and his son were lucky to get away with their lives this time.
Their task now is to realize they live in a third-world hell-hole and figure out how to extricate themselves with as much wealth as possible.
The US supreme court has ruled that the police does Not need to respond to a crime even if it happens in front of them, they are only required to police the area in general.
That was a result of a case were two women were beaten and raped. One of them managed to scream out of the window of her apartment to police officers below at the local Dunkin donuts, but the police did not attempt to save them.
Sad, sad.
