As Twitter is archived in the Library of Congress, any tweets and their metadata is, should, and can be public record... presuming your profile is marked public. Information that is not publicly displayed, such as e-mail, phone number, etc, is what should be protected - and it seems the courts have yet again failed us, granting an overly broad request for discovery. Here's the question I've not seen answered - Were Mr. Harris's tweets private? If not, I really see no problem with identifying his words and the public portion of his location (I believe twitter only presents a few, not the full, significant digits of geodata). It's both more reliable and less invasive than asking local businesses "Did this man shop here?" which is a tried-and-true police tactic.
