I'll agree on one and three fully.That's because...
1) The Jedi had had their collective heads up their asses for a long time at that point. They had become so removed from normal society that they considered themselves above the normals pretty much.
2) Like I pointed out before, the sand people are largely considered to be little more than animals. No one gives two shits about them.
3) They were in the middle of a serious war, of course they weren't going to make an issue or a fuss about one of their star players at that point. Politics saving a war hero's ass from the fire.
As for two, this was a member of the Sand People that he told. Not genetically, but this Jedi at one point was with a tribe, and he still wore the tusken raider outfit. So to him, the sand people were not considered animals, but family. His logic (IIRC) was that since Anakin will remember his actions forever, no legal action was necessary.
As for the emotions... I'll drop it.
