They made each state have a governor and a legislature (law-making body).
Laws can vary in each state.
The majority of law and order was by the sheriff, there was one in each town and he made sure that law and order was kept to some sense. He decided what happened to each criminal.
In the west though they had no laws, many people took law into their own hands. Leading to vigilante groups. Vigilante groups sprung up (in the early stages) in boom towns. the ordinary citizens attempted to keep law and order under control. Vigilante groups were later on used as a last resort against ''outlaws''.
Research 'Johnson County Wars' for a good case study.
Hoped this helped?
