The difference between them is: Arpaio obeys state, Romley does not obey state law.
Arpaio should arrest Romley and put his ass in one of those tent city jails. Make him wear pink undies, too!

You also have to look at those conviction numbers. The vast majority were plead down to misdemeanors and time served.
