I swear that Citations Needed had an episode on all the Katrina bullshit but I can't find it.
But, basically, there are a fair number of Katrina truthers who have gone over all the bullshit exhaustively, gone over how Louisiana used Katrina to gentrify New Orleans, gone over all the Chris Kyle bullshit, gone over the cops shooting random people, all in detail, but it's all in the rear view mirror because it was so long ago. But it's out there. i swear either , Chapo, War Nerd, or TrueAnon did at least one deep dive on this. I'm pretty sure Chapo or Trueanon did a Chris Kyle episode, too.
