The US has a federal system, but people are guaranteed basic rights within it. If the local government can’t or won’t protect those rights (the police abandoned one of their five precincts to the looters!), the feds have the right and duty to step in.
Posse Commitatus prevents the military from performing law-enforcement duties. The _governor_ can activate the national guard for cases like this.
