Anonymous has obtained and leaked his personal contact information, including his home address, home and cell phone numbers, email address, and an alleged home address. It's not surprising: during the so-called Cat Bin Lady incident, we saw members of 4Chan do the same thing.
A call made to the listed cellphone number was answered by a voicemail prompt which named Pike as the owner of the number. However, it also said the voicemail box was full (is there any mystery as to why?). In addition to the video, Anonymous posted Pike's information to pastebin.
The video (embedded below) said (after close to a minute of ominous music) "Dear Officer John Pike, we are Anonymous. Your information is now public domain," after which it broadcast his information, as video of the pepper spraying incident is shown in the background. The video is 10 minutes long.
Another two-minute long video (also below) has been posted to YouTube. Its author, who claims to be affiliated with Anonymous cited California law about tear gas and related weapons, basically stating that Pike's use of pepper spray was unlawful, due to the peaceful nature of the protest. The video further warns:
Anonymous is a loosely tied together group of hackers, though, and oft-times a threat or statement by one member or sub-group is disavowed by another.
