TL;DR
Trump & Barr need state & local permission for military intervention. They need the Governor's & Mayor's permission.
If the Governor won't send in the Guard, Trump can't force him to. If the Mayor orders the police to stand down, Barr can't order them to stand up.
Barr & Trump don't need permission from ANY state or local official to send in federal agents.
