Not really, you're thinking about Politicians rather than police.
On one hand, damn all lawyers! The corporation stance is stupid legal wrangling. On the other hand, I'd never become a cop due to the incredibly ridiculous amount of liability, red tape, blatantly lying "news" channels and papers, and blame for having to enforce bad laws.
Go do some ride-alongs with your local police to see what they put up with.
It's not that the SWAT officers, their commanders, or anyone else is necessarily contriving a system where they get all the power and none of the oversight. SWAT teams are very expensive to hire, train, equip, and maintain. Hence, they need to be shared by many police districts. When the state cannot organize them any better than at the county and muni level, the solution is left up to the counties and munis to work out. And this is what they chose because it was the only thing that fit, a shared cost for shared resources.
That being said, the state really needs to intervene, now that it is painfully obvious the county/muni system doesnt work, and give them a structure (joint departments) that makes it possible. There is already too much overhead from the hundreds of different law enforcement orgs that dot each state, figuring this out is a step in the direction toward making the entire system more organized, and more accountable.
