Tallbloke is one of the denialist bloggers who was gifted the latest batch of "Climategate" emails. I don't think he was near the center of the first release. In any case, the U.K. police want a closer look at his computers. Although Anthony Watts says he isn't a suspect. But if they do a cavity search, who knows what it will turn up.
PS. Horner is mostly crap, but this suggests that two other bloggers have been given "search-and-seizure" letters.
PPS. From this, it looks like Jeff Id and McI also got letters.
