Seems like this is written by a conspiracy nut. Facts are wrong (Michael Mann isn't a professor at UPenn) and the story is one-sided. There's no mention of what else Tallbloke wrote on his blog or the fact that the equipment seizure was due to the email hacking that occurred (http://www.washingtonpost.com/world/europe/uk-police-seize-e...), not because of any comments.
Here's the opposite side of the story with its own biases: http://scienceblogs.com/gregladen/2011/12/computers_of_crimi...
