This doesn't happen all the time, but when police do break the law, or don't follow it correctly their actions come under scrutiny, data collected can be discarded from court, and even suffer personal blowback.
What you're asking is how did it happen? That's because it's illegal for a citizen to resist arrest (even unlawful arrest), so in the USA if you are being arrested, SAY you do not willingly submit, but DO whatever the officer tells you.
The thing many people forget is that the law doesn't happen just on the street in the US. It is a slow and flawed process, but police are just the front line of it, not the whole thing.
As someone else said, this will probably cost the police and city in a settlement.
Edit: Cops CANNOT just hold you for 24 hours. They have to have something to charge you with even if it's disorderly conduct. And you can then sue the local police if you have evidence that you were wrongly imprisoned. It is easy for cops to get cause so your chances of this are low, but it does happen. Once detained (with cause) I believe the 24 hour bit is true.
IANAL, this is based on my unprofessional research. I'd suggest you (everyone) do the same.
It probably won't cost the police anything, it'll come out of the taxpayer.
They can, but they don't because it would be political suicide.
Can and does. I'm not saying this is indicative of what frequently happens. But there can be real consequences for the police officers based on lawsuits. I also recognize this was not being pushed down from the city. My statement was an example of how police departments shutting down affect police and how that can happen.
I won't argue that police are appropriately punished due to misconduct. I will argue that they are punished.
In a larger department, neither would have lost their jobs, and the larger insurance would have handled it.
Sexual assault is, and there's nothing a union can do to protect you from that.
You said doesn't happen. An absolute. I am saying it can happen and it's not the only form of punishment I'm referring to.
Police (the individuals) can be punished for their infractions. It doesn't happen nearly often enough (my opinion). But if you're saying it can't/won't happen I disagree with you. I'd even go so far as to say I believe you to be factually incorrect. While I will 100% change my opinion on this if given a study that proves this has never happened. It's easier for me to assert a shmeybe than for you to assert it never happens. All I need is one instance where as you need none.
Now if you want to say, that's not enough. We won't disagree at all.
This varies state-by-state, actually. Even in those where it is legal, it is very foolish, of course.
