(1) a person living in Washington state receives a large number of documents from a public records request, each containing names and mailing addresses (for hundreds of thousands of people in total), along with a variety of other data; and
(2) they then publish this collection of documents onto their own (non-commercial) website, and make tools to search/filter the database in various ways, selecting/displaying lists of individuals based on criteria from data about them in the records; and
(3) government agencies already provide all of these documents online for free download. But they only provide the records online one-by-one rather than in aggregate, and they offer limited ability to search/filter records.
Is it illegal under Washington state, or Federal, law for an individual to publish large #'s of public records containing personal information (such as home address) like this, on their own website? Would the person publishing the records likely be open to civil suits by the individuals whose information was published on the website?
