For the time being, the state should hire all the laid off Austin police, then put them in Texas State Trooper (Highway Patrol) uniforms and station them all in Austin. Then send Austin the bill to pay for them.
Then augment their numbers with police laid off from other police departments willing to relocate. So Austin would be up to its eyebrows in cops. And all working under state, not city rules.
And those arrested by them would go to state, not city, jails, under state laws, even if they are dozens of miles away from Austin.
As long as I’m not footing the bill for ‘em, I dont’t care if another agency manages them. But, I prefer that the residents of Austin get what they voted for, and learn their lesson.
