Why doesn't Posse Comitatus prevent Trump's attack on US cities?

8. Several reasons.

First, the courts have considered this and at times they've ruled against him.

He's getting away with deployments because: (1) courts take time to hear cases, and lower-court judges are reluctant to proscribe the president directly, preferring to rule and kick upstairs. (2) Trump's primary purpose isn't law enforcement but rather to provide a dramatic display of force to (a) make his base happy (b) dominate the news cycles like a dog humping a tree and (c/most importantly) provoke a response.

If you view what's going on as Trump having military parades in cities, that's not a violation. As to his being an edgelord, that's the responsibility of the electorate, Congress, and his cabinet via 25A to control, not the courts.
