I like that she is suing the police, but she needs to sue flock as well. Pain and suffering, libel, whatever you can find to make it stick. I think libel may fit very well here, "falsely accusing someone of criminal conduct is one of the classic categories of defamation per se, where reputational harm can be presumed rather than requiring the plaintiff to prove every dollar of resulting damage".
Claiming that I was the perp in a hit and run and placing me in jail has real harm and they published it to the police force.
Sure: "This plate was observed near a location under investigation." isprobably not defamatory by itself if it is factually true. However, "Registered owner is wanted for burglary." feels very defamatory with real reputatinal and potentially monetary damages. I'd want my lawyer to investigate defamation/libel along with negligence and potentially other constitutional or statutory claims depending on who supplied the data.
