As has been noted, what with people being busy with relief work, they may not be well positioned to document any unfortunate activities with federal, state or local agencies whom are getting cross threaded with private citizens horning in on their rice bowl.
And incidents may be entirely due to people being rubbed the wrong way vs official policies.
As S2 underground noted, if the agencies were doing their jobs with no issues, why would they need to spend lots of money making social media and advertising pushes to bolster said narrative?
All that noted, the DEI stuff from FEMA’s own mouths kinds makes the point for everyone.
