Who, sand people? According to Legends continuity they were.
IIRC that's only *half* right. It's more like: "according to Legends stories some of them *could* be human, but mostly on the basis that Sand People tribes would sometimes kidnap settlers and "induct" them into the tribe, whether they wanted to or not, face wrappings and all."
Personally, I rather prefer the notion that the Tuskens and the Jawas have a sort of weird, inverted "Eloi and Morlocks" relationship. In that they're both decedents of whatever species lived on Tatooine before it became an arid wasteland of a planet, with each line adapting to the massive climate change each in their own way. The Tuskens sticking it out on the surface, adopting harsh savage ways to cope with living in a harsh, savage land, shunning all bu tthe simplest of tools.
The Jawas mostly retreating underground to overcrowded warrens and cave systems, surviving by adapting what machinery and tech that survived the cataclysm to stay alive. In my mind, the ones we see up on the surface are a tiny percentage sent up to trade with between the distant warrens. Though when the first outworld settlers started showing up, they proved to be a more abundant source of trade, alowing some clans to remain topside permanently.
I know this is probably contradicted by some reference book and that it sound like I've put *way* too much thought into it, but this is just how my brain works.
The Jedi, at least before the Clone Wars, were somewhat attached to or part of the Republic's Judicial Department. They would be sent in to settle disputes. Negotiations. and other such tasks from time to time, in addition to being somewhat like roving Republic marshals, when a system's justice system was not enough to whatever what happening. The Jedi were considered fair since they were Jedi...though that changes more and more as they became seen more as overpowered Republic lackeys (partly thanks to Palpatine's behind the scenes propaganda and his own...suggestions for what the Jedi should do on behalf of the Republic). This was the old meaning of the all red Republic ships the Jedi used, and partly why the Republic warships during the Clone Wars had red trim.
Pretty sure the "roving Marshall" idea was just a Legends thing. The more recent canon materials seems to indicate that at least in the last millennium of the Order's history, Jedi operated strictly under specific mandates issued by the Senate and/or the office of the Chancellor.
I'm sure things are a little more fast and loose out on the borders of wild space or the outer rim, and Jedi do occasionally exceed their authority, but for the most part, they seem to be very passive, reactive providers of "justice". Mostly at the beck and call of politicians and bureaucrats.
I could see this not being the case in the Old Republic. Perhaps the Jedi were an entirely separate entity in a time where galactic civilisation wasn't quite as settled and the reach of the core not nearly as far, with the Jedi acting as mediators and protectors not because they're out there as deputised agents, but because that's what they religion compels them to do.
Perhaps part of the reason they retreated from this approach was because it's thought this lack of accountability at least partly contributed to, or at least helped to facilitate the Sith heresies and resultant conquests. I mean it's not too large of a leap from being the "Guardians of Peace and Justice" to "Enforcers of Order and Justice", no?
