Why would different states in the United States still manifest some different kinds of legal systems today?

-The early colonies could not agree on what other colonies decided to do with their laws.
-After the American Revolution, it took many years for some of the states to set up agencies to handle criminal offenders in new ways.
-Some territories of the United States were ruled by different countries, so elements of those countries laws remain in those states today.
-The criminal codes present in the early colonies were set up to meet the specific needs of its own citizens who believed it was weakness to accept others’ laws.
