North Dakota oil boomtown: 'I enjoy jailing bad guys'
The oil boom has been a blessing and a curse to the North Dakota city of Williston - crime is surging, women are afraid to walk the streets alone and homeless jobseekers sleep rough in sub-zero temperatures.
Williams County Sheriff Scott Busching says the number of fatal road collisions, drug arrests, physical and sexual assaults have all surged.
He told the BBC: "It can be just as busy on a Tuesday afternoon as it is on a Friday night. It's going all the time. This place hums."
