Investigation Discovery Channel is a true crime channel that knows that its audience likes a vicarious scare.  It is owned by Discovery Communications and is received in roughly 86 million households, just under three quarters of American homes with televisions.  It also tends to avoid overtly political slants on most crime issues.  At least until recently.  

Beginning last month, the channel has started a series featuring the Southern Poverty Law Center.  The first episode was about the SPLC lawsuits against the Klan.  The one this Thursday is on the Aryan Brotherhood. 

It would be more apt if I.D. focused on the scam Morris Dees and the SPLC have been running for decades separating affluent urban liberal donors from their money.
