IF "SWAT" teams are needed at all, which is extraordinarily questionable, they should be regional. Many, if not most states could get by with one for the entire state. Texas might need 2, because of the size of the state. Their budget should set by statute, and have no relation whatsoever with anything they might get during the course of call-out.
You can't have a swat team as long as you allow 'asset forfiture'.
Are there places that would need a SWAT? Like you said, about one per state. Maybe three in California. But for the most part they end up going on rides to serve warrants just to "remind people that we are useful". And it is, among other things, really bad optics.
A SWAT to raid a house with kidnappers? Ok.
For something like this? No.
Even if they had the right house, it was overkill.
