If a crime has been committed and I have information that may help them solve that crime, I will answer whatever questions they ask me; as long as I feel the questions are pertinent to the crime.
in the case in the Wired Article, the police showed up on this guys door step ...
The three men who showed up at Michael Usry’s door last December were unfailingly polite. They told him they were cops investigating a hit-and-run that had occurred a few blocks away, near New Orleans City Park, and they invited Usry to accompany them to a police station so he could answer some questions. Certain that he hadn’t committed any crime, the 36-year-old filmmaker agreed to make the trip.
The situation got weird in the car. As they drove, the cops prodded Usry for details of a 1998 trip he’d taken to Rexburg, Idaho, where two of his sisters later attended college—a detail they’d gleaned by studying his Facebook page. “They were like, ‘We know high school kids do some crazy things—were you drinking? Did you meet anybody?’” Usry recalls. The grilling continued downtown until one of the three men—an FBI agent—told Usry he wanted to swab the inside of Usry’s cheek but wouldn’t explain his reason for doing so, though he emphasized that their warrant meant Usry could not refuse.
