Judge: child porn evidence obtained via FBI’s Tor hack must be suppressed

A federal judge in Iowa has ordered the suppression of child pornography evidence derived from an invalid warrant. The warrant was issued as part of a controversial government-sanctioned operation to hack Tor users. Out of nearly 200 such cases nationwide that involve the Tor-hidden child porn site known as “Playpen,” US District Judge Robert Pratt is just the third to make such a ruling.
