...but if the nincompoop DA won’t file charges.....
Falls under a Fed DA now for those arrested by these troopers. That is how the Feds bypass the local DAs and nothing the mayor can do or the governor except to fire all these troopers but then they are still under the purview of the feds.
Nice move, they are now under the direction of the feds. Could be a good way to go, ask for help, come in and deputize law enforcement in the state, no more stand downs, no more rat governor and mayor control
