i need quotes that show injustice, and does kino get away with killing the people who shot coyotito if so i need a quote for that aswell

Which type of injustice are you looking for?

Social Injustice:

"Her arm was up to throw when he leaped at her and caught her arm and wrenched the pearl from her. He struck her in the face with his clenched fist and she fell among the boulders, and he kicked her in the side."

Injustice:

Kino hesitated a moment. This doctor was not of his people. This doctor was of a race which for nearly four hundred years had beaten and
starved and robbed and despised Kino's race, and frightened it too, so that the indigene came humbly to the door.

There is no evidence that Kino was eventually arrested or not for killing the trackers. We only know that Kino and Juana walked back to town and threw the pearl into the ocen without contact with anyone.

Kino and Juana walked through the city as though it were not there. Their eyes glanced neither right nor left nor up nor down, but stared
only straight ahead. Their legs moved a little jerkily, like well-made wooden dolls, and they carried pillars of black fear about them. And as
they walked through the stone and plaster city brokers peered at them from barred windows and servants put one eye to a slitted gate and
mothers turned the faces of their youngest children inward against their skirts. Kino and Juana strode side by side through the stone and
plaster city and down among the brush houses, and the neighbors stood back and let them pass. Juan Tomas raised his hand in greeting and did not say the greeting and left his hand in the air for a moment uncertainly.
