If an episode of Law and Order had that happen, I would call it too over the top. I'm not feeling sympathy for the mayor because she seems like she just wants it to go away without caring about the victims, but I honestly don't know what even the best-intentioned person could do about this. You're probably best off firing literally every cop and replacing the department, but I have no idea how that'd be possible.
Okay, you fire everybody. You know how long it takes to hire someone to become a cop? It ain't overnight.
So how do you patrol the city while you're "properly training" your potential replacement LEO's? Have the mayor and the common council go out in police cruisers? Throw up the Bat signal and hope some winged vigilante shows up?
And even if you decide, "oh, we'll do an investigation, and we'll fire the appropriate people," what happens to those who are left? 100 officers to do the job of 150? 200?
300?How safe do you think your city will be then? Think you'll be able to handle all the retribuitions, the #BlackLivesMatter protests, the gang warfare as the bad guys realize there ain't no one patrolling their street anymore?
Oh, and when it comes out how awful and horrible these police officers are in your city, who do you rightfully think is gonna WANT to be a police officer in your little hamlet? Andy Taylor and Barney Fife are both pushing up daisies, kids.
Sorry - sore spot. The exact same damn thing is happening to my workplace. I don't know if it'll ever recover from all the crap we've had to go through over the last eight months.
