Here's why:
* Pathos appeals to emotions. The language used ("unspeakable horrors," "police brutality") is designed to evoke strong feelings of anger, sadness, and injustice in the reader.
* Logos appeals to logic and reason. There is no clear argument or logical reasoning presented in this excerpt.
* Ethos appeals to credibility and authority. The excerpt doesn't establish any credibility or authority for the speaker.
While the excerpt might be trying to make a point about the need for change (which could be considered a logical argument), the primary focus is on stirring up emotional responses.
