@roadriverrail @flockofnazguls @th The suspicion was that it was a current or former WGN employee. I totally buy that theory. Not only did the hijacker target WGN first (only switching to WTTW when the WGN hijack attempt was foiled) but Max makes several references to WGN ("World's Greatest Newspaper Nerds," Chuck Swirsky).
I think the intrusion was a videotape and not live.
