Except unlike a motion to dismiss, merely alleging an officer to have violated a constitutional right doesn't overcome qualified immunity. To get past qualified immunity, they have to overcome a "test" of the allegation, and they have to in essence, establish that the officer likely clearly violated a constitutional right or criminal law (of a more serious nature), while outside of the scope and performance of his regular duties as a law enforcement officer. Not putting forth all their evidence e.g. in a trial, but at least be able to point to receivable details, evidence and facts that make it seem likely they can overcome the immunity at trial.

If the city attorneys are even 25% worth their salary, it won't go anywhere.
