It's quite misleading to state only that "they had evidence of child pornography that traced back to his computer network." What they (Seattle Police Department) claim to have was a tip, from 4chan, filtered through a national clearinghouse, that about seven weeks prior someone had allegedly transferred to 4chan a video of an unidentified woman abusing an unidentified child in an unknown location at an unknown time, allegedly from an IP address that they discovered was assigned by an ISP to David and that they learned prior to the search was the exit point from an anonymizing proxy network. SPD staff involved were familiar with Tor and thus knew that there was no more reason to suspect David--an outspoken critic of their public surveillance programs and other privacy-invading programs--of uploading the evidence of some woman's crime to 4chan than to suspect any of the many thousands of users of the Tor network of such. This was pure harassment.
