Many areas don't feel safe.
What's interesting is that of your list of dangerous places, only St. Louis cracks the top 10 list of counties in the US with the highest per capita homicide rate or even general crime. Aside from that and DC, the remaining counties are mostly rural.That isn't to say things aren't bad in some cities, homelessness in particular, to a degree which should be considered extremely shameful for those living in "the richest country in the history of the world".
However, the fact that the focus of reporting crime and specifically violence is nearly exclusively limited to cities is strong evidence that the goal isn't to solve the problem: it's merely to continue stoking red vs. blue division.
The underlying cause of most of the crime and violence in this country is ultimately poverty, which is why no one with political power is interested in taking steps to fix it.
