I, too, question why the authorities were looking into your bro's computer.

Charged with posession of child porn, when the only evidence is 14 filenames that could not be verified? A prosecutor admitting to "exaggerating" criminal charges? A lawyer telling a defendant to plead guilty at arraignment? (With only one hour to prepare for a case, the standard practice is to plead 'not guilty' and waive time. The plea may change at a later date - after further review of the case and discussion with the DA.) Was this in the US (what city, state)?

If the "girl tied to a bed..." was made to appear underage (even if she was over 18), and the title implied child porn, then posession of the file could be a criminal offense. But you said he was downloading music.

A program that changes the filenames as I'm downloading them is a new one on me.
