SWAT teams are municipal law enforcement. You and a whole lot of other people need to learn the structure of American government. We are a federation of sovereign states, not a single sovereign with provinces. While Washington is enormously powerful, state governments are not arms of the federal government. Key things here:
- The federal government does not control state/municipal police
- The federal government has no jurisdiction over local crimes. Zero. It has jursidiction over things that happen between states or with foreign countries. Like everyone wondering why the feds aren't charging the nigger that stabbed that Ukrainian girl with murder, it's because murder is a local crime.
- "But what about..." Several clauses in the Constitution have been used to expand Washington's power. It still doesn't own local law enforcement or local crime.
So when it comes to protests/riots, those have always been framed as local disturbances, and the reticence of blue state/city governments to do anything means it just ends with them. There's nothing for the feds to do. And yes, while you could do the grunt work to reframe it as an interstate conspiracy of some sort, which then would allow the feds to step in, the attitude of Republicans for decades has been, "not my circus, not my monkeys." Like maybe we could spend a bunch of money and time to prove that Seattle rioters and San Francisco rioters are linked, but on the other hand, who really cares? You put some people in jail, leftist judges let them out, a later Democrat President pardons them, and since the cities are still chock-full of libtards, they have no trouble producing new rioters. So in that context, it isn't worth it. And it's not like Republican voters were clamoring for a Republican President to fix Portland.
Charlie Kirk's assassination, however, has created that all-important political will to do something about the institutional, radical left. It is no longer seen as a waste of time. Nobody will complain that that the Trump administration should be worrying about taxes, not idiot kids in a blue city that doesn't even want us there.
