Climategate Crooks to Avoid Justice

As per the BBC:

The police investigation into the so-called "ClimateGate" affair is over. 

Norfolk Constabulary says there is no realistic prospect of finding the culprit within the statutory time limit of three years since the 2009 offence.

In a sense, the crime of hacking into people's emails is not that serious.  But the damage done by this theft and its resultant distortion by anti-science elements of the media could be severe.  How many people know that eight separate investigations exonerated the researchers?  (Even I didn't, I thought it was only three.)  Criminal prosecutions for those responsible might have served to send a message to those who try to twist science for their own political ends.
