Rofireinites know their place in the structure of things and the proper order of dispensing justice. No one is judge and executioner, and even judges don't make immediate decisions without a trial. That's just not how things are done. That's vigilantism, not proper law and order, and could be considered a crime in itself. It's the restraint of law and order that makes a Rofireinite a Rofireinite rather than just some random adventurer or nutjob with a sword (yeah, redundant, I know).
