There needs to be consequences for shitty, procedure-ignoring police work. Period.
Minimum 1 year of jail time for grossly wrongful arrests that could be avoided with standard procedure or investigation tactics that were not applied.
These dialogs always prompt me to chime in with my solution: make the police be self-insured, backed by their pension fund.
The police today have zero incentive to serve the public, they have zero skin in the game and can literally get away with murder.
Any time you hear the call for "law and order", that is the audience that supports the current system, because they like it like this.
I agree with this sentiment but when you start punishing this sort of thing you create more incentive to cover it up. It's a tricky problem and I'm not sure there's a perfect solution.
What we really need is a change in police culture.
