1) Do you think that Auror history may have gone back all the way to the dawn of time? do you think perhaps they might have been some kind of squad or group of trained wizards to take on dark wizards? History only of Auror only dates back to the 1970's when Voldermort's supporters were just starting to come out. Was he the only dark wizard of all time? Was the wizarding world intact before Tom Riddle turned dark? (5 points)
I think that as long as there have been 2-leggers who feel they are entitled to control others through the use of dark (aphotic - 'without light' kind of dark) magic that there have been those who felt called to block those activities and, if need be, eliminate the source of them. As long as the paradigm rules say that such a thing is possible, a 'struggle' between good and evil, there will be those who choose evil (lies) and those who choose good (true) and those who sit on the fence and choose not to choose. Whether they are called Aurors or Peace-keepers or Fragleysnacks, they exist and are active.
Sirius' post indicates that that term, though, goes back at least a couple hundred years. Who knows how long it was used before there was an actual 'official' office made for it. The world of Muggles also reflects this apparent 'need' to control those who break the law. (Of course, one has to consider who wrote the law - look at ancient Rome and who wrote the law and enforced it -- against whom.)
2) Do you feel Auror's should hold a rightful name to the Wizarding World? should we bother with the long grousam training when look what Lord Voldemort has caused even despite the Auror's fighting for protection of all Wizards and Witches? (5 points)
Aurors are present in the world. That is the name which is given to those who fight and eliminate 'Dark Wizards' and 'Dark Witches'. Thing is, Voldemort is dead. Perhaps a person who was an acknowledged Auror was not the one to kill him but at the same time, the attitude and character of the person who killed him is that of an Auror.
It's useful to have the training. Even Harry Potter had the training, even if it was, at first, mostly instinctive. Later on, there were the DADA classes. He trained himself, and more, he trained others. No, this wasn't 'official training' from the Ministry of Magic (but sheesh, look who was sent to Hogwarts 'from' the Ministry that year to be a teacher).
