Which argument does creon make to defend his decision to arrest and execute antigone?

Creon wants to arrest and execute Antigone because she went against his civil laws. He forbade everyone to bury Antigone's brother's body, because he was a traitor to the state, however, Antigone didn't listen to his orders and believed he deserved a proper burial, and not to be fed to the dogs. This is why she got arrested, and died in the end.
