They might've just lost their jobs, ended up late on rent, or going without medicine, but they were "only just detained."

These are deaths of effectively random chance, not of systematic persecution riding on the back of nationalism waving a fasces. Each one of these detentions is a policy failure and, as we live in at least nominally Democracy, there is culpability on every American unless they take any action. This weight is what bears down on people, but it seems that you are, rather worryingly, insulated or alienated from this violence.

Why are so eager to change this to a subjective matter when this directly deals with objective violence?
