Nope. Just that police are not liable for failing to prevent crime.
You can fire me. You cannot successfully sue me for the costs of my failure.

There can still be consequences, just not compensation for losses.
So...how exactly do you expect them to be held accountable? These court cases were examples of the 'democratic process' and the court ruled that the cops have no duty to help you.
